Hey Y’all. I got a quick question and would like your opinion. I have 2 - 250 gallon reef systems that run completely separate from each other. I had ich when the tanks were first started up. Lost a couple fish. Since then I have fish still in both tanks but have been running almost a year with no visibly signs of ich on anyone. Is there a chance the ich died off since I have not seen a reappearance?? Both tanks have tangs and I would think I would of seen something by now. Any advice would be greatly appreciated!!
