The SpectraPure Piggyback Upgrade Kit is a complete add-on solution designed to double the pure water output of your existing 90 GPD RO/DI system. By adding a second reverse osmosis membrane in parallel, this kit effectively boosts your production rate to 180 gallons per day. This allows for faster creation of purified water, cutting down the time required for water changes and top-offs.

This comprehensive kit includes everything needed for a seamless installation. Inside the box, you will find a high-quality 90 GPD RO membrane, a durable membrane housing, mounting clips, a precisely calibrated flow restrictor, and all the necessary fittings and tubing. Each component is manufactured to SpectraPure's high standards, ensuring reliability and efficient performance once connected to your current system.

This upgrade is ideal for saltwater aquarium hobbyists with larger tanks or those who simply want to reduce the time spent waiting for water to be produced. If you find your current 90 GPD system is too slow for your needs, this piggyback kit offers a cost-effective alternative to purchasing an entirely new, higher-capacity unit. It's the perfect solution for serious reefers who value both time and water quality.
