In the treatment tank that I am using cupramine the rocks and sand. I wonder if they absorb the copper leaving I reach the ideal level, and if he absorbs enough to saturate?
I need to know because I have to take the rocks and sand from the system.
Another issue would be on the immunity of fish treated with cupramine.
It really affects immunity to the extent of sick leave for example a cure oodiniium more fish dies by a secondary bacterial?
What spectrum cupramine? Protzoarios? Bacteria? Virus?
