question for all you chemists out there (calcium hydroxide)

[hawaiiguy]

I guess my excuse is that I'm finishing my biology undergrad right now and I've gone pretty heavy on the chemistry for the past 4 years (I could probably minor in it; haven't really checked) It's still fresh in my mind (shudder...)

I have been doing some reading at reefcentral and reefs.org and I've decided the mix I have is safe... I just dosed my tank with about 10mL of the stuff so we'll see what happens (so far, so good)...
