whats your CA/KH dosing and testing schedule?

[Ephraim]

i dose 50mL of Ca an KH 3 times daily, using randy's recipe. BRS calcium chloride is used and Arm and Hammer baking soda for KH(not baked). Mag is dosed everytime i go through a gallon of two part and mix up a new batch.

I test alk weekly, test mag when i do a h20 change, and never test ca. As long as i mix the 2 part properly and ensure the same volume of liquid is dosed in batches, calcium should remain at a constant. Alk is easier to test and cheaper so when i test for alk i can plug the result into a spreadsheet to get an assumed calcium.

Dosing is done with 2 aquamedic pumps on a timer.
