I want to start dosing vodka in my Biocube 29. I do not have a nitrate or phosphate problem as far as I can see.. but this is a SPS dominant tank and I'd like the SPS to have good color and me being able to feed the corals more.

I'm running a Sapphire BC29 Skimmer on this, not sure if that's enough for the vodka.

I also have clams in the tank.. will they be affected by the vodka at all?

Since my nitrate have been 0, how can I determine what's the daily dose of vodka once I build up to it
