okay... so the 170 KH is listed as mg/L. So is the cacium. It is a nutrifin test kit and it says optimal level of Ca is 400-425, I know alot of people are 450-475, and the optimal KH is 105-120 mg/L.
I have added Seachem calcium, powdered, at a rate of 7.5g/40gal. It says that it will raise Ca 18mg/L with each 5g/40gal dose, so I should get a little more increase than that. The maximum daily dose is 10g/40gal. I have mixed up enough top off water to last ten to eleven days at a rate of 7.5g/40gal. I should, after that period be somewhere in the 400 range.
Is this too quick an increase? Should I dilute? And where should the KH really be?
I was going by this test kit and no other knowledge. Since my questioning of it I have seen numbers ranging from 100 - 350. Bev... Ruth? Shine some brilliance on me.
Thanks
Mike
