Help with Ph, kh, & Ca levels in reef tank.

[Prince_Tony]

I have had my 55 Gallon Mixed Reef setup for about 13 months. The ph won't rise above 8.1, kh is holding at 8 and calcium at 460. Are these levels acceptable without any real damage to my tank mates?

Ph. 8.1
Salinity 1.026
Calcium 460ppm
8 dkh

id drop the cal to around 420 with a dkh of 8
Ph is fine, i only use ph as a indicator of level in alkalinity in my tank

Agreed. My tank runs around a dKH of 8-9.5 with calcium around 425 ppm and a pH of 8.1.

Those values are perfect and I see no benefit to changing them.

I discuss what I consider optimal and why here:
