What do you keep your ALK at

[nemmy]

Pretty much what the title says, what do you prefer to keep your alk at for sps corals?

Normally im around the 8.6 range, but some of my corals are being goofy so i want to try higher.

 

One of my corals shows NO polyp extension, yet it grows and is very much alive. But at the same time 3 others have insane polyp extension and great color. While one has bad color and great extension.

 

I'm going to try to find a "happy medium" for them.

my stays at 8-9 on it's own and i've lost 1 SPS coral in the 7 or so months the tank's been running

I prefer 11ish and calcium at 500 though my ph doesn't get to much above 8.1 or so
