Overview
The Australian Water Filter RO Membrane (75GPD) is a replacement reverse osmosis membrane used to restore filtration performance in a compatible RO or RO/DI unit.
RO membranes gradually lose efficiency and rejection rate over time — a fresh 75 gallon-per-day rated membrane is what keeps your system producing clean, low-TDS water for reef use.
Key features
- 75 gallon-per-day (GPD) rated output
- Restores filtration performance and TDS rejection rate
- Straightforward swap-in replacement for compatible RO units
Who it's for
RO/DI system owners whose membrane output or TDS rejection has started to drop, needing a replacement to maintain water quality for top-ups and water changes.
Setup & tips
- Confirm your system takes a 75GPD membrane before purchasing
- Flush the new membrane before first use as per your unit's instructions
- Monitor output TDS after replacement to confirm correct performance
- Replace on a schedule based on usage and output TDS rather than waiting for total failure
