Water Problem

[Randy Holmes-Farley Verified Community Expert]

Granted you would have corals melt or dissolve etc .... But what happens to the calcium in the water, the mag?? Does it not precipitate out of the solution??

Not at low pH, no. It becomes more soluble.

Now im having an issue of my alk not going up, and calcium being low.
My parameters are the following

Calcium 340
Dkh below 5
Nitrate 5
Salinity 1.025
Ph 8.4
Phosphates 0
Magnesium 1300

Sounds like more dosing is needed.
