What would be the best and easiest way to raise and maintain calcium? I have been using Kalk for a long time now, and just get tired of having to mix and drip. I use a 2.5 gal dripper, and i guess it works ok, but i can't seem to get the calcium up past 400. I'm gonna start doing some Acropora, so I want to find the easiest, yet most effective, way to raise and keep calcium up. Are the two part Kent Marine TechCB good to use? Or the liquid reactor? Thanks.
