System Comparison
Reef Pure RO Systems is Australia’s first and only RO system store that specialises in RO systems built solely for the marine aquarium hobbyist. Our products are built by reefers, for reefers. We know that there are so many other options out there and it can be confusing. Sure, a lot of the systems out there claim to produce great drinking water but just because it is drinkable, doesn’t make it reef safe.
