Should I dose?

[Fishingandreefing]

I am using Coralife salt mix, 10% water change weekly and my parameters are at around: ALk 11.5, Cal 420 and Mag 1450. (I have been testing weekly for the past month, similar readings)

note: I add 3 teaspoons of Kalkwasser in a 5g bucket ATO.

my ALK is on the higher end but my calcium seems low so I want to manually dose calcium maybe like 10ml daily

what’s your take?

I have a gallon of B-Ionic ESV calcium I got a year ago, mixed with rodi per instruction but never use it. It’s still good?

lastly, my tank is LPS dominated with some sps frags 120g with a 30g sump.

thanks

For 20-40ppm calcium, I would do nothing at all. That could also be in the margin of error.
Start dosing when AlK starts to fall, otherwise, keep her stable.

Sounds good!
