Re: various pics Thanks.
I'm not quite sure. Since they only appear when I return from the hospital I'm guessing it's one of two things. My theory is that it's either too much of something (possibly nitrates) or a lack of something. The reason I think this is because while I'm in the hospital I'm unable to change water and I'm unable to fertilize. As long as I'm able to properly care for the tank I never get the holes. |
