The AquaFX Ballyhoo S-C-DI-DI is a premium four-stage reverse osmosis deionization system designed to produce ultra-pure, zero TDS water essential for a healthy saltwater aquarium. Hand-built in the USA, this unit effectively removes harmful contaminants, chlorine, and dissolved solids from your tap water, preventing algae outbreaks and ensuring stable water chemistry for your delicate corals and fish. It provides a reliable and consistent source of purified water, forming the perfect foundation for mixing high-quality saltwater.

This system features a robust filtration process, starting with a one-micron sediment filter to capture particulate matter, followed by a high-capacity Chlorine Guzzler carbon block. The final two stages consist of dual, refillable cartridges filled with nuclear-grade, color-indicating mixed-bed deionization resin, which polishes the water to an absolute zero TDS reading. The unit comes complete with a dual inline TDS meter with a backlit display for easy monitoring of water purity, a hose bib adapter, a quick connect ball valve, and all necessary food-grade tubing, mounted on a solid aluminum bracket for durability.

Ideal for both new and experienced reef aquarists, the AquaFX Ballyhoo is perfect for hobbyists who demand the highest water quality to protect their investment and achieve a thriving reef environment. The dual DI stages offer extended contact time and longer cartridge life, making it an excellent choice for those with larger aquariums or source water with high TDS levels. The included color-indicating resin and TDS meter provide peace of mind, allowing users to know precisely when maintenance is required, ensuring only the purest water enters their tank.
