My wife bought a Pristine Hydro water filtration system (not cheap) I believe it enhances the water with minerals along with top of the line water filtration. Can I use this water for my reef tank with fish and coral Thanks for any advice
It looks like there's some water softening (adding minerals back in after filtering) after the last stage looking at their website. That's not recommended, the RO/DI portion maybe sufficient (and tap off for your saltwater/topoff) before the "softening". Not the clearest website to understand...unusually heavy in pseudoscience marketing lingo. At it's heart, looks like standard RO/DI unit with re-mineralization (common as RO/DI tastes metallic without it). Proprietary will mean a bit more money, of course. Best course of action would be to have the water tested (ICP or similar testing might be sufficient). As I stated you can tap off after the RO/DI and test that for you or finally you could route after the RO portion and then have that feed into a DI unit (2 or 3 stage) for your tank. That way you can go with bulk resin and save some bucks.
