This upgrade kit is designed to convert your existing 4-stage RO/DI system, such as the BRS 4 Stage Value or Value Plus RO/DI Systems, into a more robust 6-stage Deluxe RO/DI system. It provides a straightforward solution for hobbyists whose municipal water supply has transitioned to using chloramines, which require more comprehensive filtration than standard chlorine. The kit simplifies the upgrade process, eliminating the need to source individual components.

The kit includes two additional canisters to enhance your filtration capabilities. One canister is installed before your current system to house a dedicated sediment filter, allowing your original pre-filter slots to be utilized for dual BRS Universal Carbon Blocks for superior chloramine removal. The second canister is added after your system to accommodate a second deionization cartridge and resin, ensuring ultra-pure water. It uses 1/4" Mur-lok Polyethylene RO Tubing and is suitable for both saltwater and freshwater aquarium applications.

This product is ideal for reef aquarists and freshwater enthusiasts who already own a BRS 4-stage RO/DI system and wish to upgrade their water purification to combat chloramines or achieve even higher water purity without purchasing an entirely new unit. It offers an all-inclusive package with necessary filters and DI resin, providing peace of mind that your aquarium receives the cleanest possible water for optimal aquatic health.
