Calcium Hydroxide as KH/GH supplement
I have a planted 75 gal with DIY CO2 injection. When first planted, the standard 2 liter DIY CO2 to the inlet of a powerhead sufficed to keep the CO2 levels in the 'green'. Now that the tank has 'grown in', the setup won't budge the pH. So I redesigned the diffuser, and switched to a gallon juice jug. Now the pH is wanting to swing TOO far. I want raise the KH slightly, since it is a little low at 3.5 anyway. I've heard of (and used) baking soda as a carbonate buffer, but having kept reef tanks in the recent past, I have a large container of Calcium Hydroxide (Kalkwasser). I am having trouble locating pure Calcium Carbonate locally, and am wondering why the Calcium Hydroxide couldn't be used instead? Wouldn't the snails and shrimp appreciate this as well? Any caveats? Thanks, Greg |
