Hello all unfortunately I have been dealing with Ick for over 6 months in my display tank and finally decided to pull all of the fish out and put in a QT for month and a half. I have a couple of tangs so I know copper is out of the question so I am using the hyposalinity @ 1.009. My question is since I am using hypo does it matter if I have sand in my QT cause I have a Diamond Goby that sifts through the sand to find its food and I don’t know if I should take the sand out or is the sand ok??
