Re: Is this what I think it is???? Yup, mine was cured already before I put it in the tank, but the fungus/bacteria (what ever it is) was growing on my soil through the gravel. This is apparently a common problem with new aquariums and new organic matter. I have tried to find any info I can on the problem, but it's all vague. My SAE and corydoras have eaten what little is left in my tank.....If you have any of these they will probably make short work of it. |
