Even with an excellent reverse osmosis system, some unwanted traces can remain in the produced water. This is precisely where the AQUA MEDIC 20-inch demineralization filter comes in. Placed at the reverse osmosis outlet, it captures the residual ions that the membrane hasn't completely removed. The result: exceptionally pure water, ideal for demanding marine, reef, or freshwater aquariums.

Its ion-exchange resin penetrates deeply and effectively traps silicates. These are often the cause of brown algae (diatoms) proliferation, especially when setting up a new aquarium or after a water change. By significantly reducing their presence, this filter helps stabilize the environment and preserve the aesthetic appeal of the aquascape.

An ideal solution for tap water with high silicate content.

Some regions have tap water that is particularly high in silicates. In these conditions, a reverse osmosis system alone may not be sufficient. The 20-inch ResinFilter then becomes a strategic complement. It helps ensure the quality of the reverse osmosis water and prevents unpleasant surprises in a sensitive aquarium.

For reefkeeping enthusiasts, where stable water parameters are paramount, this filter offers true peace of mind. It helps maintain a cleaner, more stable environment, better suited to delicate corals and invertebrates.

Rechargeable cartridge and simple installation on reverse osmosis system

The filter comes with a refillable internal cartridge of approximately 1800 ml , pre-filled with nearly 1100 g of resin . When the resin reaches the end of its lifespan, simply replace it to restore optimal efficiency. There's no need to change the entire system.

Installation is designed for speed and efficiency. The filter body has a 3/8" thread and comes with 3/8" to 1/4" fittings , compatible with standard reverse osmosis tubing. The included wall bracket ensures a clean and secure installation. With dimensions of approximately 115 mm in diameter and 560 mm in height , it fits easily into a utility room or under a sink.

Composition and safety information

The resin contained in the filter is composed of styrene-divinylbenzene copolymers incorporating specific functional groups that allow for ion exchange. This technology ensures efficient and targeted demineralization.

Product classified as Hazardous (UFI: JH00-60WE-100T-TG69). Hazard statement: H318 – Causes serious eye damage. Wear appropriate protective equipment when handling resin.
