Replacement filter kits assist your RO (reverse osmosis) or RODI (reverse osmosis deionization) system in its ability to continue to run at peak performance. Filters should be replaced about every six to eight months, which means that you’ll want to keep a record of replacement to ensure that your indoor reef or aquarium are able to perform optimally. We know that you want to enjoy your indoor tank for as long as possible while providing your sealife with the best environment. Whether you need individual filters or the entire system, be sure to shop online at SpectraPure for all your reefing needs!
