Whyis my tank cloudy?

[gregzz4]

Hopefully someone more versed will speak up ...
From what I understand, if you have too much Ca, it will precipitate at higher levels of Alk, higher than yours. Say, around Alk 8.5+ or even more.

I could be talking out of my butt here, so don't take this to be any kind of solid advice, as I don't even know if a dose of Ca could cloud your water

Just thinking it could be a dose of Ca that the water column couldn't absorb, so you have precipitate ?
You'd know tomorrow as it will coat some of your hardware ...

Anyway, I doubt it's an issue of dosing/params with your Alk hovering around 6

Must be something the critters did ( jiggy jiggy )
