dosing methods?

[Myka]

Do some searching on the forums, there's lots of people discussing this. Basically, 2-part is just calcium and alkalinity, and balling is 2-part plus magnesium and trace elements. Most people doing 2-part also add magnesium.

My opinion is that 2-part plus magnesium works for most tanks. Balling is great for SPS corals. I like kalkwasser dosing for tanks with low requirements as it helps keep pH up, and helps lower phosphate (by binding it). It's easy to use and only requires one doser.
