The AquaFX Add-On Pressure Gauge Kit is an essential upgrade for any reverse osmosis deionization system, designed to provide a clear and accurate reading of your system's operational water pressure. This simple-to-install accessory allows you to actively monitor the performance of your RO/DI unit, ensuring it functions at peak efficiency. By keeping a close eye on the pressure, you can quickly diagnose issues and maintain the consistent production of pure water necessary for a healthy reef aquarium.

This kit features a durable, back-mounted gauge that reads from 0 to 160 PSI, offering a wide range suitable for most residential water pressures. Installation is made effortless with the included gauge stem and a quick-connect tee fitting, which seamlessly integrates into any existing standard 1/4-inch tubing. The straightforward design means you can have the gauge up and running in minutes without the need for specialized tools, providing an immediate and valuable insight into your water purification process.

This add-on kit is perfect for the meticulous reef aquarist who wants to proactively manage their water quality. The primary benefit is knowing precisely when your pre-filter or membrane cartridges are becoming clogged, which is indicated by a drop in pressure. This information allows you to replace filters at the optimal time, preventing system strain and ensuring you are always producing zero TDS water for your sensitive marine inhabitants.
