So lately, there's been an epidemic of bacterial growth in my tanks. I have to change the water constantly because after two days, this stuff grows a thick sheet over the top of the water! There's a clear spot where it doesn't grow that's like, three inches across, but everywhere else the stuff just keeps coming back. I bleached everything a few weeks ago, and it STILL came back.
Freed hates having a filter running in his tank (he goes into shock and just sticks to it) so I don't know what to do. The froglet tank has the same problem, and I can't put a filter on because it just blows them around like frogflakes. :(
