How often do you clean the filter sponge?

Good comments guys, yes I was asking about the effect of higher o2 on BBA, and although I know it will not kill it, it should help stop it spreading along with an enhanced cleaning schedule. Removal will only be done as said by chemical intervention of removal of affected leaves. So I think...

Brilliant thanks for the information, maybe I'll go for a skimmer as it would be good to get rid of the surface film we have. Not sure about which one yet, I like ehiem products as they seem well built, so may end up with that one. We don't have any RCS, just Amano shrimp, lemon tetras and...

So would go for the aps one? How do you fix the Eheim one to stop fish being sucked in?

Should I get a surface skimmer then? They seem cheepish at £20 for an Eheim 350. How long is yours on for, overnight only?

We do water changes every week with monthly or less filter cleans and we change about 42 litres of our 100 litre tank each week. I have an old air stone so I'll put that in on a timer to run overnight for a few weeks and see if it helps stop the spread of this algae and improves the overall...

I've been reading about BBA and it appears extra Oxygen is helpful to ensure organics in the tank are broken down better. I know BBA is potentially caused by a build up of organics so we have upped the water change to 4 buckets a week rather than 3 and also are feeding the fish a bit less. Has...

It seems to me that you had a problem and assumed it was lack of nutrients and so kept upping the dosage to try and solve the issue. I'm guessing I'm right in saying that did not work which is why you have created this thread? As already said it seems a lot of ferts for a small tank with...

okay, erm... They are on for 8 hours I think (at work at moment)

Hi, I have a 125l tank with 2x20w T8 tubes. I'm injecting 2bps of C02 and have an eheim 2324 pro external filter. The tank was setup just before Christmas and everything seems to be growing and up to about 2 weeks ago no algae. I was dosing 2ml of TPN+ and 2ml of KH2P04 daily (should be...

Think the higher temp is just down to the higher room temp now that it's warmer outside. I've been dosing TPN+ now for a few weeks along with 50% water changes and am now starting to see a change in the plants and a lot more growth. The new filter has definately helped (should have got one...

Got the Eheim 2078 on Saturday along with an extra 2 spray bars. Very impressed by the quality of the product, only slightly let down by the cheap green plastic fittings. Got the filter up and running with three spray bars along the back wall (no way there are going to be dead spots now!) and...

hehe thanks, Clive, I'm getting my new filter tomorrow, I'm putting the spray bars along the back wall pointing forward, and am just wondering if could let me know the best place to put the co2 diffusor? I was thinking at the back so that bubbles go up into the jets but not sure. Cheers

HI Matt, Yeah got a few otto's although they don't come out of the corner now, not sure if they are being bullied by the SAE's we put.

Just thought I'd post an update, I've turned up the co2, got a Rhinox 5000 and am dosing 15ml TPN+ daily with a 50% water change each week. The plants now seem to be growing a lot better than before, the algae does not seem to be spreading anymore and hair algae has reduced. There is still...

Think I sussed it ! The heater needs to be re-calibrated, I turned it down a degree from 23 to 22 and temp when down a degree from 27 to 26 - Looks like it is 4 degrees out for some reason. It used to be ok - Odd!

I also think that as a result of changing to T5 lights there is a lot more heat output from the tubes and because these are in the hood the heat is trapped and so heats the water. Last night the temp was between 28 and 29! I have read that high temerature can help algae grow, also 28 is about...

Just ordered a 2KG JBL bottle from LFS :mrgreen:

Probably have the tax man banging at the door with some new tax for c02 usage !! :o

I've upped the doseage of TPN+ to 15ml daily and turned up the C02 - (Probably have to get a larger refillable bottle now!)

Thanks, I'll try that now as I'm just about to do a 50% water change Here are some pictures of the Algae in the tank Brown - You can see some fuzz on the sword leaves at the back hair general

In order to keep the detritus out do you use vacuums (like this one http://www.aquatics-online.co.uk/addtobasket.asp?skid=2006 to clean the substrate of your tanks or just the siphon when doing a water change? Just wondering as to keep the substrate nice a clean and so help prevent algae with a...

How far do you go with the C02 as I don't want to kill the fish, at the moment the drop checker is just beyoud green going on yellow.

Looking at James' page, we have some Cladophora amongst the base of the Tennelus at the front of the tank, Brown Algae on the Java fern and Anubias, and a fuzz like algae on the sword leaves, however the GSA now seems to have gone (for now)! Thanks

The hygrophilia polysperma's new leaves do seem to be more of a brown colour rather than a nice green. I've ordered the powders, should get those by Thursday.

Just seen some BGA on the bottom :o !! and removed it. Also seem the fuzz and brown algae seems to be coming back.

Thanks for the info, however I think you may have typed in 240 US gal's instead of selecting 240 Litres as the amounts are very high, under litres KN03 is 11.15g a week, KH2P04 is 3.15g a week - :wink: Thanks again the help is much appreciated, Steve

Looking at the calculator and trying to figure out how much power of each I need to buy, am I aiming for 20ppm for KN03, 3ppm for KH2P04 and 7ppm for MgS04? Thanks

Ok, so going by the your very good dosing article, we have about at 60g tank, so we would need to dose the following 3 x a week ?? :?: KNO3 - 9/16 tsp KH2PO4 - 3/16 tsp MgSO4 - 1 1/2 tsp and the following 2 x a week CSM +B - 3/16 tsp Steve

Excellent calculator Matt, Thanks - I'll look into PMDD

Thanks for the very imformative replies guys, I've notice the flow if very slow along the front of the tank and a lot of malm, muck, dead leaves etc seem to build up around the tennelus. The approach Ceg uses with multiply spray bars at the back pointing forwards makes sense to me as you get...

Hi, 2 weeks in and after dosing 10ml of TPN+ each day, doing a 50% water change once or twice a week we still seem to have brown, hair and possible cladophora algae. I've turned up the c02 now so the drop checker is more yellow than green, the plants are now growing a lot better than before...

Here is the tank before the clean out with fuzz Algae on the swords, some possible blue/green algae on the rotala's and hair algae coming off the rotalas Played around with layout and add new wood (weighed down it kind of resembles a crab!), not sure about the aquascape yet. One thing is...

yep sure, I'll just get the tripod and camera out and post a few pictures soon. Just off to LFS to replace my broken spiro I bought yesterday and get some nice sharp JBL scissors.

Thanks, Yeah at the suggested dose of 1ml per 20l I should be adding 12ml per day. Cheers,

Just spent the last 4 hours removing algae infested plants/leaves, did a 50% water change with bucket (not sorted out syphon yet) and planted lots more Rotala Rotundifolia, Rotala wallichii, Hygrophila poly "rosanervig" amoungst others so we now have a lot more of substrate covered with plants...

Thanks for the reply, The problem is that I only have 2x54w tubes in the Roma and these are on the same control unit so cannot control the tubes separately. In this case is it best to have the lights on without a break for 10 hours? I guess the siesta thing is another way some people attain...

Hi, Thanks for the information on the python , I think I'm going to make my own one from garden hose and hozelock connectors as my sink is about 20m from my tank! I've looked through the sticky in the Algae section and cannot see any information in there pointing to how long the lights should...

I'm just wondering how people do a 50% water change, is there an easy way as that would be about 120L with my tank and will take a while using 14L buckets! Thanks,

Test Kit? - What's that !! Okay, I'll get TPN+ and start a dosing regime asap. I'm also thinking of getting substrate capsules as my Tropica substrate has been in the tank for 10 months and is probably running a little low on nutrients now.

Thanks for the quick response and advice guys, We were initially told by our LFS that Rowaphos will remove phosphate which is the cause of algae, having read some of the articles on this very informative site I can now see this is inaccurate and will remove the Rowaphos straight away. I will...

I recently decided to upgrade the 2x40w T8 tubes that came with the Roma 240 tank to 2x54w T5 tubes. At present the plants do not seem to be growing very fast and I have most forms of algae growing in the tank (e.g. hair, fuzz, green). I am using 4 kh solution in a drop checker and this...
