Chemistry conundrum

BestMomEver · Jul 15, 2018

I tested just now because I started dosing kalkwasser a month or so ago and I’m trying to stay on top of stuff. This is what I got...

Calcium 408 (Hanna)
Dkh. 12.1 (Hanna)
pH 8.4 + (API... I know, dreadful but that’s all I got. Color matching is difficult)

So how do I fix this? I like for Ca to be about 415-425.
How do I get this up wit raising the rest?
Better yet, how do I get pH and dkh lower?

Help!!

I would suggest using a less concentrated solution of the Kalkwasser . see what what the numbers are.
lets hear what others say .

Your alk is. A little high, but none of those numbers are too alarming. Bulk Reef has dry and liquid products to bring up calcium I'd you so desire. I would let alk bring itself down. Swings are worse than. The number, ime.

Ok. So no reason to panic then. I took the kalkwasser out and am using plain water in the ATO. Should I just do two part dosing until it stabilizes or just continue the kalkwasser?

Two part seems like a good option. I would test over the week and see how.much you drop though. Are you sure u need to dose yet? I'm 7 motnhs into an SPS tank and water chsnges are still enough for me.
