Maintaining calcium


New member
Question for Randy or wh ever else is around today. i am using randys alk recipe 1 for my alk buffer. I am using kent liquid calcium for my CA. My alk is running around 10.8 and very steady. I add 4 tbsp per day. My ca is running around 410 to 420. What is a good amount of the kent ca to adding per day to maintain these ca levels. 125 gallon fairly well stocked LPS tank.
