The Matrikx CTO Plus Carbon Block – 1 Micron (10" × 2.5") delivers exceptional chemical and particulate filtration for RO/DI systems. Engineered with advanced coconut-shell activated carbon, this premium cartridge effectively removes chlorine, chloramine, VOCs, chemicals, odours, and fine sediment down to 1 micron.
Highly efficient and long-lasting, the CTO Plus protects your RO membrane and DI resin by eliminating harmful contaminants before they enter later filtration stages. Its dense carbon block construction ensures maximum contact time while maintaining strong flow performance—ideal for reef aquarium owners who demand pure, stable water for SPS, LPS, and mixed reef systems.
Designed to fit all standard 10" RO/DI housings, the Matrikx CTO Plus is a proven upgrade over generic carbon filters, providing superior water purity and enhanced membrane lifespan.
