Hi guys;
My ALK is high about 14 and my Calcium is 480 my Magnesium is 1400 PH is 8 and Nitrate is 0, my question is about the high Alk is that bad and will it do any damage?
I just did a water change for my 30 gallon tank I use Nutri Seawater and RO; I have 2 fishes and all corals.

I would be concerned about your test results. Have you tested the Nutri Seawater to see what the alk. is? Are you adding anything else that is elevating the alk.? I would do another test with another test kit before doing anything.
