I am using a ton more builder than advantage.
I am also waiting for a good calcium test kit.
In a 125 gallon tank I am adding 6 tsp builder 3 times a week and 3 tsp advantage twice a week, no kalk.
the seatest kits I have read 430 ca and 3.5 alk.
I ordered a Salifert calcium kit from SWF.com, should be here tomorrow!
Do these dosages seem lopsided?
