I know 500 isn't all that terrible but I've tried to put some basic hardy corals in and they all seem to die off fairly quickly. Alkalinity is right where it should be as well.....it may get slightly low (off by 1) but never a dramatic drop in any of my levels in my tank.
A couple things...
With Oceanic salt, you're going to have Ca
levels in the high 400s from what I hear. So 500 isn't too far off from what you're doing your PWCs with. Have you tested your PWC
water just before you add it to the tank?
"Alkalinity is right where it should be"... and that number is...?
Regarding the hardy corals dieing off quickly... what corals were they? And what are your nitrate levels? If you are only doing a 20% PWC
every 2 months, I'm guessing your water parameters are not really where they should be for corals. Probably just fine for FOWLR
, as you mentioned... but maybe not for corals. What are your other numbers? (pH, salinity, temp, nitrates)
