Calcium too high

[ezerasurfr]

so my frags are not looking too great...not terrible, but not like they should.

some still have great PE, but others look almost "thin".

took Ca and Alk readings...

Ca: 520
Dkh: 7.6

not using a Ca reactor, just dosing 1 part every 4 days (or when needed). Any advice on how to proceed would be great. Thanks.

What do you mean by one part? Is it alk or cal? What's your ph?

 

[acroholicreefer]

The calcium level is not your issue. It wouldn't hurt if you bumped up your alk. What kind of lights are you running? What about flow and other equipment?

+1 bump up the alk to about 8-9, and check you mag.

Increasing your ALK tends to bring down CA so that should do it. With your ALK that low it could also mean your pH is too low as well. Dosing ALK will also help the pH. Agree to check Mg. If that is above 1300 it'll help both CA and ALK stay stable as well.
