Thanks, I live a mile away from their store and the water is $.59/ gallon at year's end pricing. Before investing in a home RO/DI system, I wanted to use their water to get a feel of the reef tank water usage. This will help decide how big a RO/DI system I'll need.
I was asking for anyone who USED their water in a reef tank and if was successful, without TDS, nitrogen, phosphate, calcium problems.
