CA vs KALKvs DOSING

[asylumdown]

If your'e going to dose, get an auto-doser. Don't rely on human machinery to do it, as that is a guaranteed way to encourage instability and an eventual mass death of coral due to alk swings.

I've been using the same Profilux doser since I started my now defunct 90 gallon. It came with two medical grade peristaltic pumps, with slots for two more (which I have now purchased). Next to my skimmer, I'd say it's the most important piece of equipment my tank has.

If you don't have space for a calcium reactor and it's associated CO2 canister (I didn't on this tank), an auto-doser with whatever size/shape dosing reservoirs for your chem solutions is the next best thing. Once you figure out how much your tank is using, they're about as 'set and forget' as a calcium reactor.
