Tiny white particles in tank

[blsnelling]

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.

Looks like you have some amazing circulation in your tank where so things just cant settle on the bottom. I run 2 filters as well 1 pulled from the bottom of the tank and the other from the top to grab stuff like that. My guess is that its fish poop...

I shut everything off for a few minutes last night, and it did all start settling. I was concerned that maybe I had a bacterial bloom or something else going on. I like a heavily stocked tank. If this is just a result of that, so be it. I'll just live with it.

I made another vid to give you a better idea of my setup.
