I purchased a Coralife Calcium Reactor package including a Millwaukee Regulator & Co2 Cylinder from J&L. I am now in need of a PH Controler to go with this Reactor. AI in Edmonton is selling a Millwaukee Controler p/n SMS122 for around $199.00. Is this a good PH Controler, is that a good price, is there a better controler for the same amount of money? I plan on buying one this week.
