Fenrir Posted June 2, 2023 Share Posted June 2, 2023 I currently own a 210gallon high tech setup( 2 48 inch fluval 3.0s Co2 system and auto water change and sump) which has been up and running for over a year. Unfortunately thing is that Wisconsin has extremely hard water. Which in turn creates heavy restrictions on what I can grow in my tank. Does anyone have ideas on how to set up an R/o system to help drop the pH to a readable level? Link to comment Share on other sites More sharing options...

Mmiller2001 Posted June 2, 2023 Share Posted June 2, 2023 Bulk Reef Supply sells nice RODI units. Depending on how far down the rabbit hole you want to go, DI might not be necessary. There's two routes you can go. Either running full RO and adding minerals to rebuild GH to exact ppm or cutting tap with RO. A third tap to RO will significantly drop the above tap numbers.
