should I start dosing calcium?

[jmack]

I have been trying for several months now to get my calcium levels down (my alk was low and I was dosing calcium so the CA would stay at 600+). Now that my alk is closer to 9dkh, it has dropped to about 520.

I am wondering when I should start dosing with calcium again? I have soft corals but the corraline algae is really taking off (finally) and I don't want to stop that process. Will I need to supplement the calcium to keep the corraline growing?

520 is still wayyy high when it hit's 400 I'd start dosing again.

Look at this. This is where your parameters should be.

How are you dosing the Alkalinty and Calcium?

BTW coralline wil grow just fine with a calcium level of 420.

Take a look at this.

Spend some time in the chemistry forum you can really get an education there.
