Kh & Ph levels for a reef tank?
 

Hi Everyone!
Can anyone please tell me what the correct levels should be for my Kh and my Ph?? At this moment my Ph is 8.0 and my Kh is at 9.

Are these levels ok for fish and corals ??

Cheers

Those are both OK, but it would be nice to get the pH up a little. Kalkwasser drip is the easy answer. Remember that there are three legs to the pH tripod: Alkalinity, calcium and magnesium. Obviously, it's not quite THAT simple, but these are the three levels you'll want to watch. If you're able to keep calcium above 400ppm, you're doing OK. And you'll hear alkalinity (dKH) guidelines anywhere from 8-12 dKH. I prefer 11-ish. Magnesium should be 1250-1350ppm.
