How long should you monitor daily consumption levels to get a good understanding of how much is consumed on a daily basis? Before holiday break a did a series of 1 gallon or so on my system (17g) to bring the Alk up to 8 with the intention to use that as my starting point to measure the daily consumption. When i checked my water before going away, my parameteres were Alk: 8dkh, Ca: 300something, Mg: 1100something (if i remember correctly, i have to double check on my notebook).
I know that Ca and Mg is low, but why? If i brought up my Alk to 8 from 7.2 during the course of a week or so, how come the other parameters are so low? I'm using TropicMarin pro Reef salt, Hannah and Red Sea test kits.
I only have 7 small SPS frags, and no coraline algae.
Could there be something taking up the Ca and Mg?
