???? PERFECT FOR AQUATIC RO SYSTEMS

For reef and marine aquariums in particular, even a good RO membrane can leave a small amount of dissolved material behind. Adding a DI resin stage gives the water a final polish before it reaches your storage tank.

Typical setup:
Mains Water → Sediment → Carbon → RO Membrane → SL10 DI Resin → Ultra-Pure Water

???? Cartridge size: 2.5" × 10"
???? Recommended application: RO water polishing
???? Target output: Near-zero / zero TDS*
