"coral snow" ... is that CaCO3 or something else?
I dump some in every time I stir up the sand or during a WC so every two weeks at least.

It is just Calcium Carbonate. I used to do it with the old tank but haven't done it since the new system is up and running. I did like the results before, so I will start doing it again on this tank.
ALOT of PVC piping back there!
