Could use some guidance on Alk and Ca levels, both optimal and maintaining. Apologies for using PPM - I know most of you use dKH.
I had been dosing Seachem Fusion 1&2 15ml every other day, but was kinda lax on testing and when I started paying more attention, I found my Alk was 124-136 and my Ca was up at 600.
I've stopped dosing the SF1 and Ca was 600 on the 5th, 570 on the 8th. What should I be aiming for? Seems like I can maintain Ca a little easier by reducing to 3-5ml once a week or so.
Alk is much more annoying. I'm testing, dosing 10ml, then testing 6-9 hrs later...results are less than consistent. Up a little, up a lot, down? Again, what should I be aiming for?
Here's where I'm at the last 5 days:
139, 140
142, 161
156, 155
150, 157
148, 154
146, 164
