{"title":"Reef Pure RO","description":"\u003cp\u003eReef Pure RO is based in Petrie, just up the road from our North Lakes store, and describes its systems as built by reefers, for reefers. The 4 Stage Essentials+ unit runs tap water through a 5 micron sediment filter, a 5 micron carbon block, a reverse osmosis (RO) membrane and a colour changing mixed bed DI resin. DI means deionisation, the final polish that takes the water to zero total dissolved solids (TDS). Each stage is sold as a replacement, and the resin changes colour as it is used up. Reef Pure also makes a Dual Media Reactor for phosphate remover or carbon, and a Dual CO2 Reactor that strips carbon dioxide from the air feeding a protein skimmer, which helps lift a low pH.\u003c\/p\u003e\u003cp\u003eWatch the TDS reading on the outlet and change the resin when it climbs off zero.\u003c\/p\u003e","products":[{"product_id":"reef-pure-mixed-bed-colour-indicating-di-resin","title":"Reef Pure Mixed Bed Colour Indicating DI Resin","description":"\u003cp\u003e\u003cstrong\u003ePolishes RO water to a true 0 TDS, and tells you when it's spent.\u003c\/strong\u003e Reef Pure Mixed Bed Colour Indicating DI Resin is a nuclear-grade mixed-bed resin — cation and anion beads in one fill — that finishes off reverse osmosis water to better than 10 megohm resistivity and a zero TDS reading.
