White dust like particles in water column
 

Just like the title says I have particles in my water column that looks like dust. Its only in the water column nothing on the rocks or corals. Any suggestions on what this could be. I know for a fact its not sand.

Micro bubbles from your skimmer ?

Nope not bubbles ruled that one out.

Perhaps one of your corals spawned. Hopefully something isn't precipitating out of your water column!

To me the usual suspects are: micro bubbles, sand, detritus, coral or clam spawn.

I have had the issue since setting the tank up its only 3 months old and its driving me nuts. If it was say calcium precipitation what should i do. My Cal is 370 mg 1200 dkh 7 Ph steady 8.2

or it could be calcium precipitate.......it can make your tank look like it is in a snowstorm

barebottom tank?
are you running filter socks? I know when i'm short on clean filter socks my water gets a bunch of debris in the water column.

Fiji pink sand tank is a rsm 250 filter sock just the polishing filter but it doesn't seem to pull the stuff out of the water. Also if you look on the surface you can see what looks like dust on the water.

Should say NO filter sock. Sorry

white dust
 

depending on how old your tank is-it could be sea snow
