snowing in my tank

[woodeye]

i have a 29 gal bio cube set up and running with live sand and rock. also have 6 sps corals, a clown fish, blue leg crab and stomatella snail. the live rock and sand is abundant with little critters as well. last night i saw what looked like pale white almost clear flakes swirling around the tank as if you dropped way to much food in there. i couldnt find the source and fished as many as i could out with a net. today the tank looks normal again. im baffled and concerned. any ideas?

What are your Cal, Alk Mg levels at currently ? Sounds like it could possibly be Calcium being precipitated out ???

Cheers, Todd

thanks for the info. ill check those levels. this "snowing" lasted about 45 mins and now i see no effects.

Are you dosing calcium and alkalinity together at the same time?

If it was at night with the lights out, you sure it just wasn't a water critter?

I would guess precipitation of calcium as well

I would guess precipitation of calcium as well

+1, to much cal will cause this. What's your level of cal, have you been dosing and what type of test kit have you been using?

if it is calcium precipitation you should start seeing a build up on your heater and other equipment
