Best news of the day!

Happy to see you continue. You are one of the most talented aquascapers ever. It isn't easy keeping plants in the great condition you manage for prolonged periods of time. Don't let people ever influence what you like and enjoy doing.

Why not make it just as tall as the substrate, plus maybe 2cm? You should be able to change nearly all the water all the way to the substrate. I'm assuming you will make the substrate leveled as there is no need to make a nice layout for this type of tank.

I have easy plants, Cryptocoryne Petchii and Java Fern Microsorum Windelov. They have only just been placed in there, so very hard to know how well they are doing. That is why I am looking for a reasonable base level for Plant 3.0 to start with. i.e. at the moment I am running at 25%, but I...

So what do you have growing in there now? And how well is it growing? Many crypts have no issue with real low light. Same w the ferns Both also do fine in higher light.

Thank you for this starting point @oreo57. Awesome. In my 100L aquarium (approximately 70cm x 30cm x 50cm), I currently use the Fluval Plant 3.0 at around 25% for whites, 15% for reds and 5% for blue). Moving closer to 50% to 75% to achieve a good level scares me a little! I guess my...

So prior to moving you used prime for 6 months without issue? It's confusing, lol. Can I suggest you change 10L of water add only 0.25ml (5 drops) of prime to the bucket that contains the water going in and gauge the reaction of the fish. I think doing the above might help us start ruling...

In conclusion to this thread, I bought and installed the new fixtures. First, I'd like to mention that when I was about to close the deal, I did a last minute safety check and discovered that many of the stores I'd been visiting online were fake... That added another layer of work to the...

HI all, In attached photo, this is my really small experimental vase like maybe a bit more than 2ltrs volume with mini air pump, with nano filter. Here is only gravel without any aquasoils. I bought limnobium levigatum, with Ludwigia, but I don't remember well the full name. I did this tank...

First you need some background in their recommended light levels: Then you need to understand LED "efficiency" (physically and electrically though the electrically part can be questionable due to led quality) is much higher than the t5's used for the above. In one estimate that would mean...

Absolutely love Corydoradinae.

Great thank you! I already have this set up in my tanks as mentioned in my initial post. My concern is just that with this set up and a full soil substrate I will nit be able to do easy water changes larger than 50% in case the need arises as I will not be able to remove the riser/pipe due to...

Interestingly, I drink boiled tap water and I’ve said since we moved in to this house that it has a funky taste. We’d bought a new kettle though as the movers lost our old one and it took weeks to find it. That “funky” taste has never dissipated and I always thought it was the plastic on the...

I used to use stress coat and switched to prime around 6mths prior to moving to where I live now.

Simon that is very kind and if you are happy to I’d be grateful. I can PM you where I live, or I can take some water and meet you halfway if that’s easier. I’m EH37

Hi all, I think it makes sense in evolutionary terms, if you aren't in imminent danger of being eaten then your best strategy is to try and maximise the amount of food you get and one way of doing that is by not "sharing". I was just admiring them <"PlanetCatfish.com - Gastrodermus...

I think I get this, and then I realise I know very little!! As most of you know, I am running a 100L low-tech aquarium. I have a Fluval Plant 3.0 32W for lighting. That part seems easy. You then purchase a plant from Aquarium Gardens (they have great plants and customer service, by the...

Hi, During years I was a big fan of EI dosing method and high light/high energy tanks, but the work involved maintaining the tank was too much for me and also never got a algae free tank. Always had massive issues with GDA and BBA. Now I have decided to take a different approach and after...

Those Nijsseni are stunning. I have some but the colouration is no where near as bold as that.

I have also found this out! My Cardinals and Black Phantoms all 'dispersed' after settling in. They seem to find their spot and only come together during a disturbance.

Another weekend, another water change. Cyanos are still present, but I dare say that they are decelerating. Really annoying to siphon it from the water surface and from the floating plants. Added a few more dried leaves. Overall, the tank is looking very stable and I don't expect to have...

Yes that is true i have checked it as well. Shall I add more? I have been looking now on my tank, and I don't know why my water is getting again hazy.... 😵‍💫🫣 I am really worried about it now... I will do some photos after photoperiod will start after 2pm. Thank you, Kind Regards, Peter,

Thanks, Darrel.

Hi all, That one. I don't think prayers will be necessary. cheers Darrel

If that's the sum total of what you added to the tank then you've added 0.04pmm Dtpa Fe and 0.012 Edta Fe (this bits from the tnc complete) Total breakdown of TNC complete:

Not sure where best to put this post, but decided here was probably most appropriate. I've been a bit of an idiot and accepted some pygmy coreys and neon green rasboras before I have my quarantine tank set up (tocotoex!). It's a 50 litre and has a sand/gravel substrate with guppy grass, java...

That small pack has 45grams of FeEDDHA. I will get some RO water and I will make solution. Yes, but I added only 0.5ml, together with 2ml TNC Complete. Actually I don't understand why TNC Complete has Phosphates together with IRON? There is a lot of opinion that IRON shouldn't be dosed...

At this dose 12.5mls in a 125L tank will raise the Fe by 1ppm, so a fairly large dose.

You could but would only need 200mg to achieve 0.1 Fe in your 125ltr tank. Alternatively you can add 2 grams into 100ml of water and dose 10mls of that, each 10ml would also add 0.1 ppm Fe.

Hi all, All I've got to say is <"just ignore them">, you are the only one who counts. I would have thought that this is pretty good ammunition to use against the doubters. <"From This to This!!!">. cheers Darrel

Hi all, Yes Platies get little red gills but i have done 40% WC as I believe because ammonia level was on constant for a few days - 0.5mg/l. But they didin't become less active. Also I am trying feed my plants. I have TNC Complete, TNC DTPA AT Iron, and Finally FeEDDHA thanks to help John...

Hi all, That is the bit that counts, keep an eye on their colour and health, and that will give you an idea of when you need to start adding nutrients (<"fertiliser">). Syphon like @simon_the_plant_nerd says. It <"should go away"> as the tank matures. cheers Darrel

Plants seem to be doing well

Hi all, What does plant health look like? It is difficult to judge <"from the photo">. Have a look at @keef321's photos in the linked. thread cheers Darrel

I think for someone new coming in to a hobby knowing nothing about CO2/ferts, EI is an amazing way to start. It's proven, tested and stood the test of time. Once more comfortable, they can then find their niche, be it lean dosing etc. Alternatively; they can start with something weird and...

Hi all, I think a lot of us probably <"end up there">. That is the rationale behind both <"Estimative and Duckweed indices">. They were developed <"entirely independently">, and have very different goals, but the underlying principle is the same "all nutrients/elements <"are needed"> in some...

Thank you, @Hanuman and @dw1305 - very insightful and helpful, as always.

Hi all, Reverse Osmosis (or rain <"If it's yellow, let it mellow and RO is the devil">) water would give you a softer water source and more of a <"blank slate to start with">. Your water supply is similar, in many ways, to what most of us get <"from the tap in the S. and E. of England">, it...

My old belief was that more light is better. And nitrate and/or phosphate caused algae and should be as low as possible. Big algae blooms in my tank were not uncommon and that's an understatement... these outbreaks are not healthy for the ecosystem and it's fish. And a lot of effort was put in...

These would definately not be the reasons why I would dillute the tap water. I would dillute it to decrease the overall water hardness which makes it harder for certain plants to growth. Also, the higher the dKH, the faster the buffering capacity of certain soils will be depleated. So if you...

Hi All, Silly question time! If you have water like mine, does it make sense to use RO (in part or in full with a supplement) to help control the number of nutrients available in the water - and perhaps limit what excess Algae can use to flourish? I am trying to understand whether there is...

Hi! Tank looks great.

Welcome aboard :)

Glad cyanoacrylate glues work while it's wet, got some lying around. Just got to work fast then. Thanks!

Actually the way the sentence is written it is unclear to me whether he has been using Prime all along. I assumed he would be using Prime everytime since he is using tap water. That's a question he needs to clarify. If he was not using prime and he was loosing fish, then definately the Prime use...

Hi there Just wanted to share my experience with another smart gadget I have just started using. It’s alternative to Inkbird digital thermometer and is called SONOFF THR16A (or THR20A 20 amp version) with WTS01 sensor. Why this one? It costs about £20 on eBay, has only one terminal to...

It's Dutch for Ricky? 🤔🤔🤔 😅

Siphon it out. Keep doing water changes. The tank is only 3 weeks old. A lot of my problems went away with water changes and patience. Cyanobacteria treatments do exist but I can’t comment on their effectiveness. Some are antibiotic based and adding antibiotics to water is usually a bad idea.

Very cool!! I heard he was coming for aquashella and stopping by the aquarium, so I commented to make sure not to miss the planted tank since its very easy to miss. Luckily he saw the last minute comment. I'm happy he liked the tank enough to show it on his channel. Yeah I don't know where he...

I’m inclined to agree with this too. The concentration of contaminants in water would ordinarily need to be much higher to cause harm to humans than to aquatic life. Perhaps bottled water is mainly drank in this household. Or, considering they are also in Scotland, they may be like me and have...

We all appreciate you Thierry :)

Added details

Agreed - the Prime aspect IS a problem, but it might not be THE problem.

Agree with @hypnogogia - I was just going to ask for some more enviornment details too.

To get specific input that will help, follow the guidelines below: https://www.ukaps.org/forum/threads/please-read-the-guidelines-for-algae-help.60672/#post-595768 There are also threads about removal of cyano in the forum.

Seems clear to me there’s nothing to loose from cha hing the prime dosing, although as @John q points out, the deaths predate the use of prime.

I'm also inclined to blame overdosing the dechlorinator. Note the instructions: Use 1 capful (5 mL) for each 200 L (50 US gallons) of NEW water [emphasis mine]. Old tank syndrome is tempting to blame and may also be a factor, but unless you are dramatically disturbing substrate on water...

🙈🙈🙈 Will it take over tank?? Can I not buy a chemical to chuck in to kill it, sorry just all new to this

No. The brown algae (diatoms) are part of new tank set up, but not the cyano. It’s hard to get rid of.

Depends what glue you are using. Cyanoacrylate will work when it’s wet, and it dries very quickly.

Is that part of the new tank process??

Looks like you’ve got some cyano bacteria there.

Hi all, It is because of sodium hydroxide (NaOH) injection. Sodium hydroxide is a <"strong base">, so it raises pH, but it doesn't add any buffering. cheers Darrel

Rotala florida

You're likely not drinking from a hot water tank though, right? So you'd not necessarily notice.

Without being the practitioner of doom I'd say the prime suspect isn't prime, the op was loosing fish prior to adding it. See text from original post. Why are the fish dying? I'm not sure. The standout clue for me is the disparity between tank ph 6, and tap water ph 8.2 average from the...

I'm often too afraid of what people think of me and my work, but I've decided to put that to one side and continue to enjoy this hobby as long as it's financially possible.

.

Exactly, why let a few folk ruin something that gives you joy, whatever that is. Especially something you have an obvious talent for ;)

Hi Sarpijk, thanks for the info! This species i have was labeled Cryptocoryne Nurii var. raubensis 'Rose Maiden' and i got it in invitro. Never heard of RM2 but you know the things with crypts, so many cultivations! Never had any luck with the nurii but this time it seems im in luck. Probably...

Little update. I've been throwing some shrimp in there. It's the red cherry shrimp that I find in my BioMaster in the other tank when I open it up for maintenance. It's quite a surprising amount! I kind of regret it because I could have gotten a different coloured Neocaridina for this tank but...

Awesome!!! This is some amazing news :thumbup: Looking forward to your new updates ☺️

Thanks for your words guys, I realized I wasn’t tired by the hobby itself but by some ppl in the hobby , should I stop for this? Well maybe not, let’s continue…

Added a Betta!

I tried but my camera wouldn't focus Sent from my SM-S918B using Tapatalk

You can also make that riser any height you like: It can be as short as you want. You can always disguise it by putting an Echinodorus in front of it or something 🙂 That way you can have it to change water, and still use whatever soil you like. If you've never installed a bulkhead...

I agree. Some research on Prime has found a few people who have had problems, and some remarks like "The sodium dithionite in Prime and Safe decomposes into sulfur dioxide. In high enough concentrations this gas can be irritating to the gills of fish. In extreme cases and acid water, it can...

Hello. Well, I had to take action once again. Since the small holes at the base of my power lift tube didn't work, I decided to run the UGF with reverse flow as suggested by @Maf 2500, in: Help needed. Miss calculation on Under Gravel Filter I didn't had a smaller power head though. So I...

And now, featured on MJ Aquascaping channel! 🎉🎉🎇🎇 Starting at min 2:27 👍

I am not sure about Paraguard - I am sure someone has some experience. Wouldn't happen to be able to catch a picture of the growth?

How do you get the water back into the tank? Hosepipe (and if so is it a food safe pipe) or individual buckets? How do you get the replacement water up to the right temperature? Do you use hot water from the tap, and if so, do you have a combi boiler (fine) or a hot water tank (not fine)?

Hi, Does anyone have any experience with Seachem paraguard and how to treat fish with it? I have noticed a small strange growth forming on the bottom lip of my fish. I think it might be the early stages of a fungal infection. I read on the bottle that you can do 1 hour Dip treatment with it...

Nurii is a species I like because once it gets going it can create a beautiful carpet! I got mine before it was commercially available from big companies. It was sold as Cryptocoryne Nurii rose maiden 2 . Originally it didn't do anything until it took off! It also creates spathes for me once or...

Thank you - hmm, sounds like a particularly sensitive species...? It's a shame as I really love the look of it. I'm glad you've got some that is working for your tank. I'll probably give it a try and see what happens.

And look what happens with my Nurii ☺️ The newest leaves are not any more green but they have the desired colouration. Pretty happy here the big operation prior to our holiday is paying off good and is not having melting crypts troughout my tank!

Pots would work fine, either terracotta or plastic. Plastic trays 50-75mm deep would be another option.

They are a good emergency back up. Filter packs up, sudden ammonia spike, population explosion makes you overstocked... a tank with that sort of planting is going to cope much better with that sort of event. You will likely need more fertilizer, but that's true whether your plants are under or...

I was uprooting some plants in my 3-month old tank and my I was unaware that my arm was putting pressure on my drift wood and it came loose (was attached by hardscape glue and tissue). This is my first tank and I am new to the hobby so perhaps the way I glued it initially was inadequate in the...

Did you see how much prime he was adding? 6x the recommended dose…! If that is not what is causing the fish dying then perhaps he should look into other options but I bet that fixing his dosing will fix his issue specially if the water is already poorly oxygenated. Also he says that the tank is...

Well... The reverse flow appears to have not been successful... The sponge I had was too dense, I need a coarser one. Today I'm gonna try to find some perlon to wrap around the power head intake. Cheers Jonni

True but normally i try to twitch my tank as less as possible. Everything goes here pretty much automatically when on holiday even feeding. The only thing my best friend does is grab a beer, checking the system for leakage ,check if the feeding goes right and enjoying the tank 😁 He also checks...

Thanks to all @Horizon Aquatics for having us, the selection of plants is second to none including a few I have never even heard of before, and thanks to any UKAPS team involved with the organisation Including and especially @Geoffrey Rea and @Ady34. It was also good to catch up/meet with other...

Here's what I think is happening. From the article I linked above. The consequence of depleted carbonate in the aquarium water is twofold. Firstly, it can adversely compromise how fish regulate the minerals in their body through osmoregulation. In itself, this can be deadly. Secondly, without...

The supply of anything but the most basic of aquarium plants is sporadic in my country, and usually the more exotic/attractive species come in only once in awhile if at all. Supplier's cite low demand and high minimum order quantities as the reason behind refusing to import the nicer plants...

Wish you all the best going forward, thanks for the work you've put into this great site!

I honestly have no idea, but if there was a problem with the pipes you’d be sick too. For that reason alone, I’m not convinced it’s a house thing. Deoxygenating with prime is a good suggestion too. Maybe do a water change without prime by aging and see what happens?

I thought about this @Tim Harrison, too. But the ammonia and readings were all very low. Maybe more 'Sick Tank Syndrome' - if not the prime and other aspects.
