RO3 AKVA LINE is a complete, 3-stage reverse osmosis system for aquaristics with a membrane AQUAFILTER 100 GPD. It provides an output of up to 370 l/day (at 6 bar and 25°C) and removes up to 98-99% of contaminants, including dissolved compounds and microorganisms. The set is ready for installation and includes, among other things, a 5 m hose, brackets, a sewer clamp, and a PL instruction manual.
RO3 WATER FILTER AQUARIUM OSMOSIS AQUAFILTER 100 is a complete reverse osmosis system for aquarium use, designed for convenient installation and effective water treatment. This reverse osmosis filter with an AQUAFILTER 100 GPD membrane delivers a capacity of up to 370 l/day under 6 bar and 25°C conditions and removes 98–99% of contaminants. It is a practical osmosis filter for users who want a clean base for further adjustment of aquarium water parameters, with a full set of installation accessories and a Polish-language manual.

In aquarium keeping, water quality directly affects tank stability, the condition of fish and plants, and the ability to accurately set target parameters. RO3 AKVA LINE has been developed as an effective water filtration system for aquarists who need repeatable results and a high level of purification.
The reverse osmosis used here is one of the most advanced filtration methods. As a result, the device helps reduce the presence of unwanted substances in the feed water and prepare water that can serve as a base for further mineralization or mixing according to the needs of a given stock.
The unit operates as a complete 3-stage filtration system. Water first passes through the pre-filtration stage, then reaches the osmotic membrane, which is responsible for the main separation process of contaminants. The whole system has been completed with a suitably selected flow restrictor supporting proper operation.
Original pre-filters help extend membrane service life and maintain high filtration efficiency over longer use. The use of the proven AQUAFILTER 100 GPD osmotic membrane translates into very good water purification results for aquarium applications.
The filter is intended primarily for all types of aquariums. The purified water can serve as a base for further adjustment of parameters suitable for freshwater tanks and other setups where limiting the amount of contaminants present in the feed water is important.
Thanks to the high filtration efficiency, the user gains greater control over the quality of water used for changes, preparing blends, and stabilizing aquarium conditions. This is a particularly useful solution where repeatability and the ability to precisely shape final parameters matter.
Important: the declared capacity of up to 370 l/day applies to test conditions at 6 bar pressure and 25°C water temperature. The actual system capacity may vary depending on pressure, water temperature, and feed water quality.
The system is used to improve water quality using reverse osmosis. To maintain filtration efficiency, regular inspection of the pre-filters and membrane is recommended according to usage intensity.
RO3 AKVA LINE is a solution designed for convenient start-up. The system is assembled and prepared for installation, which makes setup easier and shortens the time needed for connection.
The set includes the components needed for installation, so the user receives a practically ready water filter for aquarium applications. Each unit also comes with a Polish operating and installation manual.
The whole set is packed in an attractive, elegant box.
