    Default Need urgent help with BBA please

    Hey Guys, I need some help with BBA and the setup is as follows. I'm running makemyleds on my 1600ltr tank and I'm automatically dosing macro and micro nutrients daily. I got the recipe from Grubs at aquariumlife.com. My LEDs are running at 30% for 5 hours and I have just down some tests and the nitrate is 25 and the phosphate was nearly 10. So I'm assuming this is to high for low to medium plants with no co2.
    Do I need to back off my nutrient dosing to every 2nd or something? I have tried to add 50 Darwin shrimp and 6 Siamese algae eaters but they only lasted 4 days with one of my fish eating them all. I'm going to treat the tank with no more beard algae but long term what is the solution. Any help would be appreciated the plants are growing great but I need to get this algae under control.

    Cheers Axl

    Hey dude, how bad's the problem? Any pics?

    Definitely reduce your nutrient dosing and do a few large water changes. Do you gravel vacuum? if so, do more. Also clean the filter.

    You can spot dose with peroxide, glut etc or whole tank dose with the one-two punch method.

    I find that BBA is something that appears in tanks with driftwood until the tank is mature (say first 6-12 months). I do think there is merit in the idea that BBA can be associated with DOC (Dissolved Organic Carbon) buildup in tanks with lots of wood, and tanks that are not maintained as frequently. I spot dose with peroxide but if it gets too much I go for a low dose of gluteraldehyde using Aquagreen's Dino Pee for the whole tank - not trying to blitz it in one go but rather I'll do a lower dose and then hit it again 24 hours later.

    Swapping water/filter media from a mature tank can accelerate the maturation process.... which is really all about building stable microbial communities in the tank matched to stable water chemistry.

    BBA can get a foot hold in any tank i have found and the amount of ferts or nitrates does not have much of a bearing on it. Grubs may have it with the DOC build up although i did get some going in my outdoor tank over winter and it was getting a really good flush with the winter rains. It does have a lot of driftwood in there.
    My solution is just to do the maintenance on the tank, WC, trim etc and spot treat the BBA. Doing the time consuming parts of tank maintenance is just part of owning one.

    I've been battling BBA in my tank since it was about 6 months old... The tank has a massive piece of driftwood as the centrepiece, but it doesn't lack maintenance by any means. It gets a 50% WC weekly without fail on a Wednesday. Recent changes to the CO2 disolution have helped, but its still present. I still don't think anyone fully understands BBA and how to kill it. The most common answer I've seen is keep your CO2 stable (and high) and keep up maintenance. Both of which I'm doing, but I still haven't stopped it growing altogether...

    As a side note, the fish in tank are thriving - discus, elephant noses, glass catfish, and other community fish. Elephant noses and glass cats in particular won't do well in poor water conditions. Some of my favorite plants just do not work in there though - I can't grow tiger lotus or lileopsis despite them both growing like mad in my old tank with the same substrate, similar levels of Co2, ferts and similar hardness.

    I agree no one fully understands BBA. I have reasonable success with Glut on a daily basis. Also I use high light for fast growers and no light for slow growers. Problems seem to occur when slow growers get high light so I try to shade them in a high light situation which helps. It's medium light intensity tanks that seem to have the biggest BBA problems in my opinion.

    There is a classic thread on BBA on ukaps. It shows how little we understand about each of our algal enemies. Most data have been extrapolated from Eutrophic natural systems and they don't really translate to our small closed systems.

    I’ve had great success with double dossing exel... there can be issues for other plants but it can get a whole tank under control. If there’s only bits and pieces using hydrogen peroxide squirted directly onto it at water change time. It fizzes and turns pink and dies, it’s very satisfying
    Im just a little bit crazy

    Noddy - mind sharing the actual dose/litre? I’m keen to try it. I’ve got elephant noses in my tank though - think they’ll be ok? Ive killed one in the past using h2o2 on my old tank back in Perth...

    It’s basical a double dose of Excel. Normal dose is 5 ml /40 litres do double dose is 10 ml/40 litres. Use with caution though, I know that Val dies when this is done but not sure about others. Do a google search and /or an Aquarium life search. I think that someone started a list a few years ago with sp. (plant and animals) that don’t cope with it. Also realised I spelt excel incorrectly in a previous post ��
