ideal alkalinity for coral tank

[sand9e]

I run mine at 8.5 dKH. No problems. Red Sea Coral Pro salt, 20% monthly water changes, and a calcium reactor. Simple.

Thanks for the advice, everyone. I'll try slowly raising to 9 dKH and see how the SPS respond. My calcium's at 410, mag at 1300, so those should be in line. Appreciate the help!
