Calcium problem in 130D

[Snowman]

Hi all.
I'm having a problem raising my calcium. I have been using Reef Complete. My calcium is at 360. When I started the dosing it was at 320, I have also used a PH buffer previously, my PH and DKH were holding perfectly, but since I've been adding the calcium, they have been dropping. I know the 3 are somehow related, but there has to be a happy medium somewhere. Any ideas?

What's your magnesium? If it's low you will have trouble keeping ca and alk where you want them. There are other possibilities (e.g. bad test kit)' but that is a likely cause if everything else is ok.

higher the CA lower the DKH...and vice versa....

WVUreefer,
Then how do I find a happy medium. I do have to raise the calcium, so how do I keep the DKH where I want it?

Next time give more info

Calcium =

Alk =

pH =

Magnesium =

You may have been raising your calcium just to slowly. You can raise the calcium 50 ppm / day
