I seem to be using an insane amount of 2 part (Two Little Fishes A/B). About 70+ml a day. Thing is I only have a 20L with 15 gal sump. I do have a big clam (Deresa) 7", fair to good coraline growth, and about 10 frags ranging from 1.5 to about 3". It seems like a lot to me but I have no reference. I dose about 20-30ml 2-3X a day to try and keep levels stable. Alk into the sump and Ca into the display. My Ca is still low (340, and alk/DKH is at 10.6 Salifert) Am I missing something?
