The Bulk Reef Supply 4 Stage Value Plus 200GPD Water Saver RO/DI System is an essential piece of equipment for any serious aquarist, delivering up to 200 gallons of pristine, 0 TDS (Total Dissolved Solids) water per day. Designed specifically for reef tanks but suitable for all saltwater and freshwater aquariums, this system effectively removes contaminants from your source water, providing the clean foundation necessary for a healthy and thriving aquatic environment.

Key features include advanced Water Saver technology, boasting an efficient 1.5:1 waste-to-product water ratio, which significantly reduces water waste. It comes equipped with a dual inline TDS meter for real-time water quality monitoring, a flush kit to extend membrane life, and a glycerin-filled pressure gauge for optimal performance. Installation is a breeze with Mur-lok push-connect fittings for leak-free connections, and it includes 10 feet each of blue, red, and black tubing. The pre-installed NSF certified filters comprise a True Gradient Technology sediment filter, a chlorine carbon block, two 100 GPD RO membranes, and high-quality color-changing mixed-bed DI resin, all in standard 10 x 2.5 inch dimensions. The compact 16" x 7" x 15.5" design makes it ideal for tight spaces, and it offers versatile connections for both faucets and garden hoses.

This 4-stage RO/DI system is perfectly suited for aquarists whose homes receive city water treated with low amounts of chlorine, or those with relatively clean well water, where its robust filtration ensures contaminant-free water. It's an excellent choice for reefers seeking a reliable, high-production unit that's easy to install and maintain, whether for permanent setup or temporary use. Backed by a BRS Limited Lifetime Warranty, this system provides peace of mind and the assurance of consistently high-quality water for your aquatic inhabitants.
