AF Demineralization Resin 1000ml

Description

Ready-for-use the highest quality resin for demineralization of water. Created specially for reverse osmosis filters, mainly as the last stage of the tap water purification. Demineralization Resin is perfect for the production of fully demineralized water. It guarantees water free of silicates, carbon dioxide and other contaminants.
Dosage: Place the resin in the filter as the last stage of filtration. The resin should be replaced when the TDS begins to indicate more than 001.
Worth knowing: Causes serious eye irritation. Wash hands thoroughly after handling. Wear protective gloves/protective clothing/eye protection/face protection. IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. If eye irritation persists: Get medical advice/attention.

AF Demineralization Resin 1000ml as your RO/DI final stage

This colour-changing DI resin sits as the last polishing stage after your reverse osmosis membrane, taking your output the final step to zero TDS. For Singapore reefers and discus keepers this stage matters more than people assume, because our chloraminated tap water still carries silicates and dissolved solids that an RO membrane alone does not fully remove. Feeding a reef or sensitive freshwater tank with truly demineralised water removes one of the most common sources of stubborn algae and creeping parameter drift.

Replace the resin once your inline TDS meter starts climbing off zero rather than waiting for a fixed time interval, since membrane condition and our local feedwater quality both affect exhaustion. Handle it with gloves as the label advises and rinse hands afterward. A spare 1000ml on the shelf saves you scrambling when a water change is due and the meter has just ticked up.
