My tank has been fully cycled for months. All fish are healthy. However, I've had these white particulates in the water for a few months now. It's never worse than this, and never goes away. Yesterday, I vacuumed the gravel and cleaned both filters. I did two 50% water changes. It's no better than it was. I checked the levels for fear that I could have induced a mini cycle, but all looks good there this afternoon. What gives? I want a crystal clear tank.
BTW, there are two canister filters: Ehiem 2217 and Fluval 406.
