[Enigma]

Someone who is very knowledgeable about reef aquariums has suggested to me that I raise my Alk to 12dkh, in an effort to eliminate some of the algae I have in my tank.

Are there any risks to raising the dkh that high? I'm already raising my mag and dosing h202, so I'm not afraid of a bit of risk . . . I'd just like to know what the risks (if any) are before I decide to do this.

Mostly LPS, with a few SPS and softies. Mexican Turbo and spiny Astrea snails. Blue Tixedo Urchin. Occelaris, green chromis, Bangaii cardinal, twin spot goby.
