ok a few more Q's-
should i have a deeper sandbed? right now i have very little sand in there, maybe 3/4" (if that) deep. ive read a deeper sandbed helps with nitrate controll.

what the heck is calk??? i hear about everybody dosing it... but i dotn think i need to bury my head in all that calcium stuff untill im ready for corals... right?

also, i figured out my lighting, im getting a 130 watt fixture

also whenever im rewady for corals, how do you attach them to live rock? or do they come attached to a small piece of rock?
