failure to thrive

[marie]

I had similar problems with a bucket of I.O. bought last june at J&l. the corraline algae stopped growing first than i started losing my montis and my lps. By xmas my tank looked horrible. It took many water changes with new salt to bring it back. Interestingly the bad batch of salt tested at only 3.5 dkh and no cloudiness when mixed so it took me a long time to blame the salt.
