RO3 75GPD aquarium filter

The simplest aquarium osmosis system equipped with two prefilters (carbon and sediment). A modern system by UST-M, ensuring clean, soft water free from nitrates and nitrites, chlorine, and many other impurities.


All connections used in the filter are made with original quick couplings from Organic with additional locking clips, minimizing the likelihood of them disconnecting. Inline cartridges also have outlets adapted for use with quick couplings. When replacing cartridges, there is no need to dismantle the couplings (as is the case with the cheapest Chinese filters) but only to unplug them. The product is manufactured by the renowned Polish company UST-M.

We supply the filter as a complete device, ready to be connected to the water system.


The complete filter consists of the following components:
1. RO3 reverse osmosis filter
2. 75GPD osmotic membrane
3. water connection
4. flexible hose
5. water discharge clamp to the sewer
