Comments: I ordered this kit and also got the 25gpd CP1811 CAPTIVE PURITY HI-SILICATE REMOVAL TFC REPLACEMENT MEMBRANE and it fit my Coralife PURE-FLO RO unit perfectly! I ran it for 2 hours as the instructions said before using the water and the TDS reading was very low on the output. Will keep this kit in mind when I need replacements again!

Comments: You can't beat these at these prices. One small issue I had with the carbon block filter was the rubber washers tend to come off. Take care when replacing them that they stay in place on both ends.
