1.5Gal (7L) NUCLEAR GRADE COLOR CHANGING DI RESIN – BRS is mixed-bed deionization (DI) resin made for the final stage of an RO/DI water system. After reverse osmosis reduces dissolved solids, the DI resin removes remaining dissolved ions to help drive Total Dissolved Solids (TDS) down to (near) zero for aquarium use. This resin is especially convenient when you want a visual indicator of exhaustion, since the media changes color as it is used up.
Features:
- Used as the last stage of an RO/DI unit to help reduce Total Dissolved Solids (TDS) after RO processing
- Color-changing design: media is reported to change from blue to brown as the resin is exhausted
- Helps you monitor replacement timing visually, and also complements TDS meter checks as TDS begins to creep through
- Designed to be used with a refillable DI cartridge system (not single-use proprietary cartridges)
- Packed for freshness in sealed, foil-lined 4mm Mylar bags to preserve quality and shelf life
- Sold in bulk/quantity sized resin to support economical refilling of standard cartridges
