Lavender Posted June 16, 2023 Share Posted June 16, 2023 So, I live in a area with extremely high GH, numbering above 500 GH, and don’t like any of the hardwater fish (I plan a amazon river biotope). So I’m buying a RODI system. The saltwater folks say to buy a Spectrapure, but that seems fancy, since my only goal is a lower GH and PH. Would the Koolermax work for me? 1 Link to comment Share on other sites More sharing options...
Biotope Biologist Posted June 16, 2023 Share Posted June 16, 2023 Yeah I would just buy a simple home RODI unit. You can add minerals back in if you want pretty easily. 1 Link to comment Share on other sites More sharing options...
Lavender Posted June 17, 2023 Author Share Posted June 17, 2023 In that case I’ll just buy the Koolermax. Link to comment Share on other sites More sharing options...
