RO3 aquarium filter, 75 GPD

This reverse osmosis unit suits aquarists who prepare their own water for tanks and need to remove nitrates, nitrites, chlorine and other contaminants from tap water before use. It is supplied as a complete kit with two prefilters and a 75 GPD membrane, so it can be connected to a water supply and drain without buying additional parts.

Why it matters

• Two-stage prefiltration: a carbon prefilter and a sediment prefilter sit ahead of the membrane, which protects it from particles and chlorine.
• Quick-connect fittings: the connections use Organic quick connectors with locking clips, which reduce the risk of a fitting coming loose under pressure.
• Cartridge replacement without disassembly: the linear cartridges have quick-connect outlets, so they can be swapped by releasing the fittings rather than unscrewing them.
• Ready to install: the kit includes the housing, membrane, water inlet fitting, flexible hose and a drain clamp for connecting to the sewer line.

What it works with

The unit is designed for aquarium water preparation, where it produces the low-nitrate, low-chlorine base water used for mixing and topping up tanks. Its 75 GPD membrane rating and the included prefilters are the key parameters to check against your system and water demand.
