water clarity?

[Obsidian]

I am having trouble keeping the water in my planted aquarium completely clear. It has been this way for months, and nothing seems to change it. It is tiny white/opaque particles. The result is slightly cloudy, but not noticeably so unless you look carefully. Bacteria bloom? It is not green water. I've tried a number of clarifying things, but none seem to help... and I know that they work, because I used it successfully on a different aquarium. The other thought I had was that it was from the DIY yeast reactor, which lines directly into my powerhead.

Here are the tank specifics:

78F
6.6 pH
5 dGH or 89.5 ppm GH
25 gallon tall eclipse
floss only over empty eclipse carbon cartridge (no carbon)
aquaclear powerhead
DIY yeast CO2 reactor... silicone line through checkvalve, into top of powerhead
bi-weekly water changes at 10-15%
heavily planted with hornwort, swords, a cryp, a banana plant, and moneywort, and some kind of tall eelgrass-like plant

neons, serpae tetras
sunset platys
spotted or speckled or something cory
CAE
african dwarf frog

Hmmmmmm.... curious. Couple of thoughts.

Has your DIY bottle ever tipped? I knocked mine over by mistake once and, over the course of an hour, got my fish quite drunk on the raunchy stuff. The yeast would certainly cloud the water, and may do it for a while.

Is it bubbles from the powerhead/CO2 mixing? Fill a big glass of water (or gallon jar) with tank water and let it sit for an hour or so. If all the water clears up (ie, the white things have all floated to the top and disappeared) then you have supersaturated gas. The plants can do this with oxygen. Is the tank worse in the evening or morning? Do you turn off the CO2 powerhead at night (a very, very good idea)?

Other than that, I have no clue.....

What are the ammoina, nitrite, and nitrate levels?

Never tipped the bottle. I am inclined to think that it is supersaturated... it all rises to the top. I will try settling some water in a glass. As for the powerhead, I keep it on all the time. I used to force the CO2 through a ceramic airstone. The powerhead works better... but I had the particulate problem back in the airstone days too.

I am a little embarrassed to admit that I have not tested for nitrate. I don't have solution for that in my master testkit. The ammonia and nitrite are undetectable.
