Kalk Drip

[Werbo]

Started a kalk drip yesterday using a 2.5 gallon container. I loose about 1 gallon per day to evaporation. What rate should I set the drips. I started at a drip every 5 seconds.

My tank is a 90 G with 100lbs of LR with 2 shrimp and 2 chromis (just starting). How much kalk should I add to the 2.5 G mixture to maintain Ca and Alk at ideal levels? Right now my levels are 10-11 d/Kh and 430 ppm for Ca.
