Never got round to posting but near the end of last year my 600 thermo leaked and drained 75% of the contents of my 180L tank on the floor. I got the updated top housing some months before that but I never did find the root cause of the leak. It seemed like there was almost too much pressure...

I have one of these as a secondary filter in my tank alongside the bigger biomaster 600 thermo. The heaters in the oase filters do seem to make noises when they come on and off but obviously the frequency of that happening depends on the room temp and your target temp. It is one of the quieter...

I’m just using a right angle bend on the pipe myself, no spraybar or lily pipe etc. At the moment just using the standard oase ones but soon I will upgrade to steel pipes. I have two filters so one on each end angled appropriately. The outlets are just far enough under the surface to not be...

No mechanical timers but I know the sound you mean. I just have one digital timer for the co2 and it’s silent apart from the relay coming on and off on the schedule. It definitely seems to come from the heater

Hmm yeah most of the comments about that in that thread are mine :D I just wanted to surface this properly to see if anyone knows of a way to stop it happening or something

https://www.dropbox.com/s/ky9cyc3y7uby87s/IMG_0160.TRIM.m4v?dl=0 Here is the clip, you may need to turn the volume up :)

hey folks, just wondering if those of you with a thermo filter from oase (filtosmart or biomaster) have heard a period weird noise from the filter? I’ve determined this is the heater but not sure if it’s a sign it’s bad or not. Both my biomaster and filtosmart do it. I have a sound clip...

Thanks for all the opinions guys :) Yeah true about the clogging, that’s why I’d only use it in my secondary small filter. Carbon I haven’t used for almost 2 years now but did have a bit of mild sickness with a couple of the fish so had to treat. They are all better now! I think what I will do...

Hi folks, just picked up an Oase filtosmart 100 thermo as a second filter for my tank. Nothing too fancy but it should help with the flow and some extra filtration! I intend to use this filter for my chemical filtration (purigen and carbon when needed) and polishing, along with skimming. I was...

True. I think the skimmer set for 12/16 pipes was £25, should be fine for import

The skimmer one I found one AliExpress, I can’t recall the search I used but I’ll find the product page later. The normal one I bought from aquasabi. As it’s going to be for the main filter I wanted it quickly and any issues I know I can get support etc.

It’s the 600 thermo. I’ve had a few issues with it, like a weird noise every so often, but the main issue was constant purging of bubbles. Every 10-15 mins it would do this and no matter what I tried it continued so in the end I changed to a different filter. I’m hoping this new head solves the...

Interesting! I didn't know about "fake" amanos, will have to watch out for them. Generally I only clean once every 1-2 months, but with the crypt melt the filter is getting clogged fast even though I am taking the dead leaves out as often as I can. About half of the plants in my tank are...

I got in touch with Oase again and they will be sending me the new design so hopefully I can use the filter again and remove this ugly heater from my scape :)

Hi guys, thanks for the replies and feedback! Based on what Tom has said I think I will skip the eheim part. In the end I decided to buy some chihiros metal pipework: The outflow has a joint so you can swivel it round. I'll use some extra jubilee clamps to make sure they don't come loose (I...

Thanks for the offer :) what I mean is right now with the jbl filter I find the flow is perfect without the spray bar, just describing the current setup really. When I did use a spray bar in the past I found all my shrimp would just hang around on it all day rather than actually help clean the...

Hmm good idea but I am very paranoid about leaks after my HOB on my previous tank dumped the contents on the floor overnight stepping down to 16/22 would end up restricting the flow, probably not by much but it would be notable I reckon?

I have thought about that Jay but the 1902 uses 19/25 pipes instead of the normal 16/22. I have yet to find an in-line that will fit that size. The combined flow rate of a biomaster 600 and filtosmart 100 would almost match the jbl, with the advantage of being able to shape the flow a bit with...

Nice find, thanks! Certainly looks like it might fit the bill and doesn’t look too offensive either. I’m thinking of adding an oase filtosmart 100 at the other end of the tank, alongside the biomaster 600 so hopefully that would be enough flow in total. Really limited on cabinet space but I can...

Interesting! Looks like a new way of clamping the impeller cover? Yeah I think air getting in due to blocked inflow can be a common thing in every filter. I had some crypt melt recently and it clogged the inflow pipe and the filter was blasting air out every few minutes. Previously with the...

Ah cool awesome! Were there any visible signs of changes? I wonder if I get in touch with them whether they would swap mine out as I complained about air issues a lot.

Oh right interesting! The size for the biomaster would be standard 16/22. I am not too fussed if it's plastic etc, just anything that would help get good flow around the whole tank

Did you ever find out more about this? I am thinking about switching back as the internal heater (although possibly a bit flawed) would free up a decent bit of space in my new scape

Hmm I think any special food I add would be gobbled up by the mollies pretty sharpish! You may have a point about roadworks, there are some houses being built at the other end of the village. I'll see if I can find out more. Could be... I wonder if some of them were just reaching their...

Ok so this might be a shot in the dark, but is there such a thing as a right angle lillypipe? To explain more, my tank has a rim and a lid, so in the back there are two locations for pipes to go in an out. If I was to use a standard lillypipe then it would be pointing towards the front of the...

It’s 200L (plus 15L for the filter). For the plants I use TNC complete at 21ml a day and the shrimp get fed an algae wafer or some hikari shrimp pellets every now and then. Generally there’s plenty of bits of algae and scraps for them to eat (I’ve seen them fend off fish to keep hold of food...

hey folks, I seem to be having a lot of amano shrimps dying lately and it’s really stumping me as to what is happening. Every few days I’m finding one of my amanos all pink and dead on the bottom of the tank. Today I found one scooting around the bottom pretty much upside down. It seemed to be...

I have that one, had it for about 9 months or so I think (since I started properly aquascaping) and it’s been perfectly fine. Hardly seems to get dirty in my tank so I only clean it every now than then. A good tip for reading the colour accurately is to place something behind it while reading...

Interesting, maybe I need to soak it more? The bazooka I have has been working great so I guess I’ll keep using it until it gives up :) What kind of tetras are those? Never seen red/orange ones before!

Strangely I switched from a bazooka to a flux one and just couldn’t get many bubbles out of it. The bazooka does a fine mist but the flux seems to struggle (40 psi). I would say those styles of in tank diffusers are the best if you are looking for something a bit stealthy as they are easy to...

Was this an expired FE? I am using them now as a cheap co2 source so interested to see this

Seeing as the external will be larger than the internal, you should be pretty well placed for space so would be best to put the old media in the new filter.

Is the new head suppose to solve the air issue? When I ran that filter I also had that issue sporadically. I still really wish they would do a higher flow rate version, not a fan of having the heater in the tank :(

Good to hear it was sorted. Oase definitely know about this as I contacted them directly when it happened. I’m pretty happy with my jbl filter now, just a shame I have to have a heater spoiling the view in my tank now :(

Hmm I wasn't sure if it could be stag horn without branching! I have been cleaning my filter every 2 weeks recently, it's never really that dirty. I guess it's just down to the recent substrate change (it's triggered crypt melt so I guess that is making it worse!)

I had this happen randomly overnight in my biomaster 600. Hadn't done anything the day before to cause it. This does seem to be a weakness of the filter design... I lost pretty much all of my dwarf gourami over the following 48 hours as a result (this happened in winter and the tank become...

Reassuring to know I'm not the only one! I went from 6-7mm gravel only to tropical soil only and that has really knocked everything out of sync, just hoping the crypts recover. Going to try the glut spray advice. I try to avoid chemicals these days, but sometimes you have to do what you have to...

Hi guys, does this look like thread algae? It's definitely not stag horn as it isn't branching, just really long single strands that are growing quickly. I recently replaced my gravel substrate for tropica soil and the crypts are melting at the moment (presume due to parameter changes caused by...

Actually found a decent kit today https://www.dfrobot.com/product-1782.html This is part of dfrobot's "gravity" system which is a shield you can get for an Arduino. It also works with their "lattepanda" single board computers which is awesome. I have one of the original ones they release a few...

Cheers for the link :) I might give that a go! I don't have any ph stuff at the moment, but I think I need it to try and work out what's going on with my co2 due to all the algae!

Yeah I too haven’t found one that does logging. I could always get a cheap one from amazon and maybe set up a raspberry pi to photograph the display every 30 mins, but that’s kind of a pain lol

hey guys I was wondering if anyone has a recommendation for a device that can automatically log ph to do a profile with. Either off the shelf or diy is fine (I’ve got many Arduinos and raspberry pis kicking about). I’m not usually able to hang around all day to take readings so I think a...

Looks like the algae is coming back with a vengeance again! A couple of weeks ago I deep cleaned the tank, got rid of any plant leaves that were algae covered, scrubbed the hardscape, gravel cleaned etc, turned the lights down in intensity, shortened photo period by an hour, upped co2 slightly...

Looks like Fluval have released an update to the 06 series filters today: https://www.fluvalaquatics.com/uk/07-series/ Anyone plan on getting one? I was rather hoping they might come out with a new "507" or something with higher turnover (in the 2000lph range), but looks like it's just...

Hi guys. Not tried the bleach method yet but I will if soaking it in the tank for another few days doesn't work (put a different diffuser on at the moment). Forgot to write the pressure in the first post, but it's around 40-45 psi :)

Hi everyone I recently replaced a bazooka diffuser with the flux diffuser from co2art. These are more or less the same aside from the clear fittings on the newer flux model. However I have noticed that even with the needle valve all the way open on the new diffuser, there is no more than 2bps...

I often run my lights in blue mode in the evenings for a few hours just after the main photo period. This helps for extended viewing and the blue light is set to a very very low intensity (5%) to avoid any algae issues, but is enough to just light it up

I'd say medium, but if you double up then high :)

Charterhouse are ok but their returns aren’t great. I sent back a broken filter and it took over two weeks to get a refund. Staff seemed polite enough but it just didn’t seem organised. Aquaristikshop is probably the worst I’ve dealt with. Plenty of communication before I bought the items and...

Well I got the Aquasky lights and fitted them but honestly the colour temperature looks way off even when adjusting manually. I wasn’t expecting great things but I don’t think I could live with them all the time. They will do as a temporary measure for now while I wait for a new controller from...

The first pic also looks like a bit of stag horn algae too?

Yeah I have noticed that in the past with bursts of stag horn. About a week ago I did some trimming and removed most of the stage horn from the crypts and it doesn't seem to have come back :) It's just the dreaded BBA as usual, it's the only type of algae I am facing regularly now, I hardly even...

Hey, so this may be a dumb question, but I have heard people say before that fertilisers should always be kept in opaque bottles as it prevents the light from affecting them. Is there any truth in this? I am auto dosing and just drilled a hole into a water bottle to use as a container, so it's...

I have this too. I think it's fairly normal? I suppose if you ran an airstone overnight for a few hours it would go darker / blue by the morning. I also have just a small surface ripple on my tank, haven't noticed any fish gasping (have been a bit worried sometimes about the mollies coming up at...

Should have updated this thread earlier as I have had another failure of the light controller :( I have ordered 2x Fluval Aquasky lights instead. Whether those will be any good or not I don't know as they aren't really aimed at planted tanks in particular. I do think it's the lighting that is...

Yeah, in all fairness they were good when I dealt with them. I never got as far as a refund or anything though as eventually I just gave up on the filer due to the poor flow rate (it's sat in the shed as a spare just in case). I really hope they redesign the biomaster sometime, there are lots of...

I also had that bubble issue sporadically. Sometimes it was fine, other times it was chucking out bubble every 10 mins for weeks. Oase also didn't know what the issue was in that instance.

I'm using a JBL e1902 on my 200L, lots of flow and media capacity. Biomaster 600t is also a decent choice if you want a built in heater, but the flow is a bit on the low side imo.

I think if Oase would make a 2000lph filter with the bio master design and a 300-500w heater they would sell a lot of them. I think it’s a good designer and has plenty of media capacity but the flow rate is just too low imo

On the tank end, I'm just not a fan of the friction fit style (fitting the hoses over the inlet/outlet without any clamps). I'm probably just paranoid, but after having a leak once before I will always prefer a solid feeling connection. The optional upgraded intake and outlet weren't that good...

I tried mine with removing the pre filter pipe and sponges altogether and it honestly made very little difference to the flow rate from what I could tell

Throwing my 2 pence into the ring. I did have that eheim filter briefly but it was damaged out of the box and wouldn't prime (the little flap snapped clean off). Apart from that it did seem like a decent filter, though I wasn't a fan of the intake and outlet (I don't use glassware myself, I...

Thanks for the info :) I am very tempted to switch to them. I did like the lights when I was using the 1.0 version, but not being able to automate them is what led me to switch to the eheim setup (which I regret now lol). Another option I have found is the easy led system from aqualantis...

Hi guys, I was wondering what options there are for us folks with T8 hoods. I have an old aqualantis 200L tank which has 2x T8 tube fittings. I haven't actually used the T8 fittings for a long time as I have been using some LED replacements for a few years, superfish retrofit (budget option)...

Well this just keeps getting better. I received a replacement controller directly from Eheim. The clip to hold in the light connector was broken... I then received another replacement and now that one appears to have bricked itself like the original issue. Do not buy these lights or...

Wow that’s quite incredible :) I have a 200L tank and should have about 20-30 amanos (I think my mollies ate a few little ones) and I can usually see maybe one or two during the day but if I look really closely the others are often scurrying around in the plants and such. They seem to be holding...

Drat, that's about an inch too wide for my cabinet :(

Just thought I would touch back on this topic as it's been a while. I have slowly added more amanos and they now seem to be thriving since I changed my filter and removed the spray bar. They have plenty of places they like to hang out in gourds, but I often see them out and about exploring and...

Just been trying to find a source of co2 more local to me (currently using Adams gas, nearest one is quite a trek) and tried Home & Office Fire Extinguishers Ltd as mentioned on here before. They are selling 2kg fire extinguishers for £7 which is a bargain! They are in the Saffron Walden area...

Hi mate, I just checked mine and it roughly matches the second set of diamensions. Couldn’t check to the mm as pulling it out is a nightmare lol. I really like the filter, just wish it was quieter.

Should have included this in the OP, but I believe it was definitely triggered by lighting problems I had, the controller for the lights died and everything spiralled (warranty replacement also broke). As my lid is 2x T8 fittings I had to retrofit the LED lights and 2 are too powerful so the...

Yeah the flow rate is night and day! While I feel the build quality and noise on the oase is better, the flow was just dire and that meant running minimal media so the water was never that clear. I am on a 200L tank, fairly heavy stocking with fish. Have only cleaned it once since I got it and...

Hmm it looks like it, but it is all single strands, none of them are showing the stag horn type pattern. It seems most if it is coming off with just a scrub, so I will keep doing that and dose excel for a while

Has anyone got one of these and can measure it up? I'd like to see how it compares to the biomaster in terms of size, thinking of replacing the cabinet on my tank to accommodate a larger filter.

Haven't read the whole thread yet, but just thought I would chime in. I have changed my oase biomaster 600t for a jbl e1902 and the flow rate is night and day. The water has never looked clearer as I can now have a big wad of floss in one of the trays. What I don't like is that the jbl sounds...

Hey guys, still fighting my battle with algae, but it seems to be starting to take over again. Does anyone know what kind of algae this is? I have seen some BBA in the tank, but mostly on the hardscape items and only in patches - this was my main issue for a long time but has been getting under...

Thought I should update on this lighting system. Unfortunately I now have a major project with them - the controller has completely died after we have a small power cut the other day. The lights won't power on and it doesn't connect to wifi... Very annoyed to say the least

Thanks guys, that has reminded me that I have some anti vibration mats in the shed! It’s helped a little bit but it’s still a touch loud, I’ll reduce the hose length tonight and see if that helps. I’ve removed the spray bar for now and pointed the open outlet towards the back of the tank and...

Finally got everything in place! It’s a rather beastly filter even though it’s fairly narrow and tall. The larger diameter pipes are quite a handful, but I think once cut to length they will be ok (I am using them full length for now while I check the filter). Inside of the filter is nice and...

On the topic of my JBL filter, first I was sent the wrong filter, today it was swapped by DPD for the correct one and there is a part missing! Useless!! I'm flipping annoyed to say the least. Might as well have spent the extra £20 odd and bought it from a retailer that knows what they are doing.

Wow that’s quite bad really. Early this year when mine broke they didn’t know what caused it but they spoke to the Oase rep about it. I was never told the cause, but presumably they knew about it. In the end most of my fish were alright but I lost 2-3 as a result in the following days. As much...

Well my JBl filter arrived today, but they sent the e902 and not the e1902... have to ring on Monday. That’s interesting, must have been what happened to my heater then!

Yeah I got a steal on it! It was already down to £205 then there was about 10% off that. I’m keeping my fingers crossed it will be worth the money. The aquael units look decent, the pre filter is nice and easy to get at if that is a consideration for you. Oh dear! Has it leaked the water out...

Was looking at those the other day, they look good but the flow rate is a lot lower than the JBL :( I've just ordered the JBL e1902 as I managed to get it for £180 which is quite a deal, will hopefully get it set up and running over the weekend, so I am eager to see if it puts and end to my...

I have considered this filter myself as it looks like a good new filter design, but unfortunately it's just a few cm too wide for my cabinet :( The only ones I can fit in mine are the biomaster, eheim and jbl. My tank is an old aqualantis one and the cabinet is similar to the pic below. It's...

Yeah I had read they use larger pipes, presumably that's partly enabling the higher flow rate as it can push more water through the pipes? I don't use anything inline or any particular inlets / outlets on my tank myself so it isn't really a consideration, but I guess it would make it awkward for...

I am still getting air in periodically but it's not too bad (liveable). My mine gripe is the flow is dire and I don't know what is causing it. I cleaned all the filter gear and am running on the bare minimum of media and most the tank is still devoid of decent flow. I am running no pre filter...

On the topic of eheim filters I’ll just say that I got a Professional 4 a few months ago (I think it was the 350t) and it was broken out of the box and wouldn’t prime. The valve was snapped clean off. So as much as I like eheim that was kind of off putting lol

I seem to randomly get phases of the filter burping out bubbles. It’s really strange. Right now it’s been fine for 3 weeks but today it’s started again. Unfortunately I’m limited on my filter choice right now due to the cabinet I have. Hopefully going to get a roma 200 soon and I’d either go...

I haven’t yet but I will have a look at that, thanks! I’m currently running without the pre filter foams and minimal filter media but even then it’s not great. I measured up the aquael and unfortunately it’s about 1cm too wide for my cabinet :( I have a 200L tank but the cabinet design is...

I’ve just looked this filter up a result of your post and it looks great from what I’m seeing so far. Currently I have a bio master 600 thermo and I’m in two minds about replacing it. I had one fail after just 2 months and although my current one is ok the flow rate leaves something to be...

Thanks for the input guys! I had a sneaky feeling that this was causing the algae to take over!! As a quick fix I have just killed the blue light in the evening, later this week I will adjust the timing of everything so I can still get a few hours viewing in the evening by having everything...

Hey guys, so I have been trying to think of ways to control my algae problem lately. I am getting a combination of several types, most commonly dreaded BBA... Right now I am using an 8 hour photoperiod (which is 7 hours full intensity with 30 mins on each side for sunrise/sunset) and then after...

Thanks for the tip about your media setup! I've arranged mine in a similar fashion now and the flow rate has definitely improved somewhat. I think the slight leaks I was getting was due to the media bottlenecking the flow and it was forcing water out of the seals slightly, since I have cleaned...

Well today a 3rd one appeared lol, still 2 down but hey :)

Well only 2 of the 5 are now hanging around on the spray bar but the others are nowhere to be seen. I’ve just done a thorough trim and tidy of the tank today and had a good look in all the little hiding places and they are nowhere to be found. I can only assumed they have been eaten or maybe...

Thanks for the tips :) I'm going to try cutting down the lighting and double the water changes if I can. My ludwiga at the back of the tank are pretty tall and do cover a fair amount of the surface at the moment, I'm going to refrain from cutting those back for a while

Well I got 5, 2 were larger and 3 were smaller. I often see the larger ones hanging about on the spray bar, but the others are nowhere to be seen! My mollies will try to eat ANYTHING. They are greedier than the goldfish I used to keep previously (and that's saying something). If I ever add new...

Thanks for the tip :) I am trying that now to see how I go. I am still getting issues with air and even had some small leaks so this really isn't giving me any confidence, especially after the heater problems I had before :(

5 for £15 near me, but fairly small to medium size. I think mine may have ended up as an expensive snack for my fat greedy mollies :( Does anyone know where I can get large ones from?
