BGA Help

I had BGA when I first set up my aquasoil tank. I had to kill it with EM, and it hasn't come back. I think the cause might have been high levels of dissolved organics. My nitrate was ok, and so was my circulation. But the aquasoil leached ammonia and a bunch of organics, and along with some melting plants in the tank the BGA showed up.

So, maybe the tank has gotten dirty lately, or there are some decaying leaves, debris, etc., that needs to be taken care of. Or maybe some more frequent waterchanges.

Either way, those are my thoughts/experiences. Good luck keeping that nasty BGA at bay!

Blue green algae love light. When I get some it usually starts where the sunlight hits the tank, usually at the bottom next to the substrate. By adjusting my window blinds I can keep the sun off of the tank, and don't seem to get BGA at all then. Low nitrate concentration in the water can also encourage BGA to grow, so making sure you dose enough nitrate helps too.

 

All my serious diehard cases of bga started in tanks that had too much organic waste rotting in the substrate....but the only way I've ever been able to solve it permanently after the fact was by reducing lighting. Doing EI helps too but cleaning the substrate thoroughly and reducing lighting was totally necessary for me to get anywhere with it.
