    Hello everyone,

    I have a blue-green algae breakout and I want to get rid of it. It was really bad until I lowered the light down to 4 hours a day. I read that you can use hydrogen peroxide, so I was wondering if any of you have had any experience with it. I have taken pictures of the progress. These pictures are actually good progress believe it or not hahaha.

    hydrogen peroxide is pretty toxic towards your fauna, IMO buy "erithromycin" from local pharmacy, break the tablet into half an' dose it with a small water solution once daily for next one week. It will be gone in no time..;)

    Too much food (organics, nitrates) for the BG algae in the water. That wood in the tank - is it clay decoration or real wood? Take it out and try to nose - it might have started to decompose. In case wood is OK, then probably you overfeed your fish.

    The decoration is fake. I have not been feeding my fish for the past week. Only in very small amounts every other day.

    If I may ask, what is a fauna? Unless you are talking about my java fern. :)

    I would never advise dosing antibiotics on a tank, firstly, because black outs work better and secondly because of the fact they play holy hell with the biological capacity of the tank. + they're illegal in large parts of the world, not to mention the whole superbugs from miss use of them argument. If you search the forum there are a lot of discussions on BGA, it's a very very easy thing to remedy, do a black out for three days. Clean the tank, filter and everything else, the root cause could be one of a few things but most likely poor maintenance and poor flow, potentially low kno3 but this is less common than poor maintenance and also low co2. Increase the maintenance, clean things more thoroughly, reduce feeding/make sure the tank isn't over stocked, make sure the filter is big enough double check dosing and co2 and see how it goes. If it comes back, increase the maintenance again and increase the flow, as a last resort increase the kno3 dosing, providing that it wasn't out of line originally. Below are two links, one a thread discussing BGA the other a link to the most reliable algae info. http://www.aquascapingworld.com/threads/bga.6117/page-2 http://www.theplantedtank.co.uk/algae.htm

    Deva3d, I would point you towards James c's excellent algae guide to identify the algae and the cure.

    I strongly suspect your problems to be related to your co2, 1 bps means literally nothing as a measure, the tank by having algae is telling you that you need more co2, a drop checker would be a good investment. I also suspect poor maintenance and potentially insufficient ferts. Increasing the plant density would also be wise, rather than chucking out the plants replant them and double the plant mass.

    Are your lights on timers? 7-8 hours make me wonder. Stability is the name of the game, put your lights and co2 on timers.

    First of all manually clean up as much as possible. Increase circulation and CO2 in the tank. Check if you have any "dead zones", usually those areas are where BGA will start from before spreading. Also clean up your filter and sponge because that's where lot of the debri can start collecting over time. With the plant mass visible in the pictures the tank seems to have too much light, so that might be another change (less light, not just photo period till you get a decent amount of plant mass or add more plants).
