RO/DI Water

Keep your reef thriving with ultra-pure RO/DI water, produced on-site using the same Trace Zero filtration we rely on for our coral farm. Each batch is filtered through Trace Zero 1 µm sediment and carbon cartridges, a high-rejection RO membrane, and colour-changing mixed-bed DI resin to deliver consistently clean, low-TDS source water.

• Made with Trace Zero filters – sediment, carbon, RO membrane, and DI resin for high-purity output.
• Ideal for reef aquariums – perfect for salt mix, water changes, and evaporation top-off.
• In-store only – available exclusively for local pickup at New Dawn Aquaculture.
• Bring your own containers – we’ll fill them for you on-site.
• Consistent quality – produced from potable source water and polished to ultra-low TDS.

Maintain stable water chemistry and reduce unwanted nutrients and contaminants by starting every change and top-off with properly filtered RO/DI water made on Trace Zero filtration.
