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 AKVA LINE is a complete, 3-stage reverse osmosis system for aquariums, equipped with an AQUAFILTER 100 GPD membrane. The set has been designed for convenient installation and effective water treatment for aquarium applications. It offers a capacity of up to 370 l/day at a pressure of 6 bar and a temperature of 25°C, and removes up to 98–99% of contaminants, including mechanical particles, dissolved compounds, and microorganisms.
It is a practical solution for people who want to obtain highly purified water as a base for preparing the right parameters for an aquarium. The set includes, among other things, a 5 m hose, brackets, a drain clamp, and instructions in Polish.

In aquatics, water quality has a direct impact on tank stability, the condition of fish and plants, and the ability to precisely set parameters. RO3 Aquafilter 100 is a reverse osmosis system that effectively reduces the presence of unwanted substances and prepares water with a high degree of purification.
The device uses the reverse osmosis method, regarded as one of the most advanced water filtration technologies. Thanks to this, the system is primarily suitable for all types of aquariums where consistent water quality and the possibility of further remineralization or mixing according to the needs of specific livestock are important.
The system has been designed as a complete, 3-stage filtration setup. Water passes through preliminary purification stages and then through the AQUAFILTER 100 GPD osmotic membrane, which is responsible for the main contaminant separation process.
The use of original pre-filters helps extend membrane life and maintain high filtration efficiency over a longer period of use. The manufacturer uses branded, proven osmotic membranes that achieve very good filtration results.
The filter is intended mainly for all types of aquariums. Purified water can serve as a base for further preparation of parameters suitable for freshwater tanks or other configurations in which it is necessary to reduce the amount of contaminants present in the feed water.
Thanks to its high filtration efficiency, the user gains greater control over the quality of water used for water changes, preparing mixes, and stabilizing conditions in the aquarium.
Important: the declared capacity of up to 370 l/day applies to test conditions at a pressure of 6 bar and a water temperature of 25°C. In practice, the actual system capacity may vary depending on pressure, water temperature, and feed water quality.
The system is designed to improve water quality using the reverse osmosis method. To maintain filtration efficiency, regular inspection of the condition of the pre-filters and membrane is recommended according to the intensity of use.
RO3 AKVA LINE is a solution designed for convenient start-up. The filters are already prepared, meaning assembled for installation, which makes installation easier. Each device comes with Polish operating and installation instructions.
The set includes the components needed for installation, including a 5 m hose, brackets, and a drain clamp. This means the user receives a complete system ready to connect.

It is a reverse osmosis filter intended mainly for aquarium applications. It works well in all types of aquariums as a system for preparing highly purified water.
The device capacity is up to 370 liters per day. This value applies to test conditions at a pressure of 6 bar and a water temperature of 25°C.
The system removes up to 98–99% of contaminants present in the water, including mechanical contaminants, dissolved compounds, and microorganisms.
Yes. The filters are prepared and assembled for installation, and the set includes the necessary accessories as well as instructions in Polish.
The set includes, among other things, the AQUAFILTER 100 GPD membrane, a 5 m hose, brackets, a drain clamp, and Polish operating and installation instructions.
Original pre-filters purify the water before it reaches the osmotic membrane. Thanks to this, they protect the membrane, support its effectiveness, and help extend its service life.
Yes. The actual amount of water obtained depends, among other things, on pressure, temperature, and feed water quality. The more the conditions differ from the test conditions, the lower the capacity may be.
Yes. Reverse osmosis water is often used as a pure base for further preparation of parameters in line with the requirements of a specific tank and livestock.
