Since the all was well till about 3 weeks ago when my clown picked up ick. I tried supplementing the feeding with garlic but continued seeing decline over the next week. Finally when he had welts and white patches over one side of his body I set up a qt and added copper. The ich spots seemed to clear up almost overnight.
Next I bought a new hydrometer so I could use one for copper. Before testing the copper qt, I compared the hydrometer readings...holy cow what a difference. One was measuring 1.026, the new one remained pegged to the top. I ordered a refractometer and found it agreed with my old hydrometer. I have since checked a few times and have came to the conclision that both hydrometers are off. I am guessing the salinity swings may have had something to do with the clown picking up ick.
Neither my diamond goby or algae blenny showed signs of ich the entire time.
