HELP!!!

Calcium fell out of solution last night when evaporation led to pump pumping air bubbles everywhere.... How do i fix this??? Will corals be affected? It looks really weird to have "snow" in a fishtank.....

Several water changes are in order. If the snow (calcium ) is covering the liverock vaccum them when doing the water changes. I also would like to know the calcium and Alk levels? Also if possible a mag. level would be interesting to know.

How does "Ca fell out of solution led to pump pumping air bubbles"? Me think you got your water level in the sump too low. If this is the case, just add more water and the tank would be OK.

yes that is exactly what happened, the bubbles were just a side note, i guess i wasnt clear. will the Ca re-(whatever the word is) into the water, or do i need to go ahead and add some more? (Ca)
