Im wanting to figure out my water before trying to breed. Did a search on what tds meter to buy and found Russ @ Buckeye Field Supply in threads here helping people out. So I looked up his site and gave him a call. Russ was very easy to talk to and helped me select a tds meter, pH meter and calibration kits.

Next call will be a million questions to select and figure out RO units

Thanks to Russ
