Kalkwasser Dosing Trying To Zero It In

[Bohicas Reef]

Been dosing Kalk for about 4 months now, slowly increasing the volume so not do too much too fast. I am currently dosing 12500mL daily. Total water volume between display, frag and sump is 600 gallons.

PH average now is 8.07 (APEX), top line is 8.2. Last night PH dropped to 7.88 (not sure why) has not done that in weeks.

Current ALK 10.24 at 1230pm (not dosing)
CA: 421 last test 1211pm (30mL per Hr)
MG: 1305 last test 1212pm (dosing 5500mL daily)

I have a mixed reef tank. Frag tank holding more mini acro colonies.

Thanks for the help and advice in advance

Welcome to R2R!

If your alk is at 10.24 dKH and not falling, I would not increase the dose any more than that. If alk is higher when you check in a week or so, then you should back off a bit.
