Hi everyone,
1. I just purchase 120 gallons 6 feet long and it is rimless on the top, the bottom does have rims so my question is: should I have a euro-bracing at the top? if yes, does anyone know a local custom glass store?
2. My RODI seems to increase TDS very fast while the resin stills remain mostly black. I changed carbon filter last week, sediment about 1 month ago. It's a 4 staged BRS RODI system. Please advise.
