Thanks guys,
As the tank maturing, the ALK, CA, and MG intake is increasing at a rate such that I think I might need a CA reactor. I'm dosing about 200ml of ALK, and CA a day and about 100ml of MG. I use the BRS salt and have a standard 10 gallon with baffle so each sector is about 3.3 gallons. So every two month, I have to check the supplement tank and refill. Not too bad so far but if the rate keep increasing, I will not be able to keep up. I've ran CA RX on my previous tank before and it was a constant adjusting also. I'll be getting the electronic regulator and the a masterflex peristaltic pump if I go the Rx route.
