On a side note, I have had 3 fish die within the last 3 months it seems where before I had none. And it started after I began using Fluval ClearMax. I got it and phosguard on a huge sale, like 3$ when normally 10 or around that kind of deal.
I did not use the phosguard due to mixed reviews I read. Clearmax also removes phosphates though, can doing that or using claarmax in general cause issues?
The first two fish died within a week of using first packet, one fish was so bloated I could literally see through it.
The other I am not sure what was wrong, probably died from seeing the other fish looking so crazy. The bloated one I tried putting in epson bath, but it died in the bath. Then I had another danio also dead approx 2 weeks later, no signs of injuries or bloat. And now this one, granted its tail was bit off but I have noticed it looking like it was maybe starting to get that bent back, not bad but definitely seemed to be curving.
Obviously totally unrelated to the missing tail, unless being weak makes them a target. Anyways, clearmax is the only thing Ive changed and seems to be or coincidentally wrecking havoc.
