Maybe I jumped the gun on treating my tank. I just know I've been trying hard to get the tannins out of my tank and just when it started looking clear, I had to begin treating the water for ick and yep, the medication is an ugly brownish yellow color. So now my tank is yellow again. =( I still have a couple of days to do the treatment but now I'm wondering if they ever had ich to begin with. I noticed 2 small white dots on one of my cardinals tail fins... almost looked like little tiny bubbles... I think they're still there but none of the other fish has symptoms. Should I finish with the treatment or do a water change now?
