Update: Calcium Plus is now avalible in 3 sizes, 500ml, 1000ml and
4000ml (1Gal.) sizes. The new 1 gallon size is perfect for "dosing pump" style maintanace programs. Reviews are fantastic, tons of people are telling me the same thing, their results are great with these products, sps colors become amazing and coraline algae growth is unreal.
Thanks for viewing,
Brad
