How balance high Cal with Kh?

[Kamila89]

Hi! Everybody! I’m still confused how I can balance it out my CAL with my KH?
I tested my Kh and Cal for the last couple of days and the readings are
Cal:480/500
Kh:7
Ph:7.8/8
Po3:0.11 I need to bring it down
Nitrates:0.5
Mag:1380
Those are my usual numbers but I wanted to raise just a bit my KH/ph so I only dose Fusion 2, 2 days ago and got it to KH:8.4 and Ph about the same. I tested again yesterday and it declined to KH 7.6 so I dose again and I got back up to the same kH:8.4 my Cal still the same and Mag after only use Fusion 2.
My thing is,I’ll have to dose everyday fusion 2 to maintain the #? It’s ok just using fusion 2 for now or I’ll have to use Fusion 1 too? If so when? I haven’t dose Cal because it’s pretty high already so I’m dosing what I need to bring up but am I doing it right? 8 months tank, low nutrients system, just LPS.

You'll need to bring your Ca down in order to increase Alk (and avoid abiotic precipitation). You can do this through water changes. Ca at 450, Alk at about 9dKH, and Mg at 1400 is the current accepted range. BRS did a video on this a few months ago ... google that and see what you think.
