AQUARIUM REVERSE OSMOSIS WATER FILTER 75GPD + REPLACEMENT
SO-RO3-X4-75V
Rating
3-stage reverse osmosis filter RO3 AKVA LINE for aquarium applications with a 75 GPD membrane. Effectively reduces contaminants (up to 98%) and helps achieve water with lower conductivity, pH, and hardness (depending on the parameters of the incoming water). The ready-to-install set includes 2 sets of spare inline cartridges (WPL2 and WWL2), a flow restrictor, hoses, a drain clamp, and a Polish instruction manual.
Description
AQUARIUM REVERSE OSMOSIS WATER FILTER 75GPD + REPLACEMENT is a complete, 3-stage reverse osmosis filter for aquarium use, ready for installation and equipped with a 75 GPD osmotic membrane. This osmotic filter effectively supports water treatment in aquariums, reducing up to 98% of mechanical impurities, dissolved substances, and microorganisms. The set also includes 2 sets of replacement inline cartridges, a flow restrictor, hose, drainage clamp, and Polish installation instructions.
RO3 system for aquariums – ready to use
This is a complete reverse osmosis system intended primarily for all types of aquariums. The filter is factory-prepared for installation, making setup quick and convenient. The whole system is based on a proven filtration arrangement, in which the pre-filters protect the membrane, while the membrane itself is responsible for very precise water purification.
The reverse osmosis system is one of the most advanced methods of improving water quality. In practice, this means effective reduction of unwanted components, helping obtain water with parameters desired in aquaristics.
Key advantages of the RO3 system
-
Proven, efficient, high-quality branded osmotic membranes deliver very good filtration results and feature a long service life.
-
Original pre-filters purify the water at the first stage, protecting the osmotic membrane and extending its lifespan.
-
A specially selected flow restrictor supports proper system operation.
-
The set includes Polish operating and installation instructions.
-
The filters are already prepared and assembled for installation.
-
The whole set is delivered in an elegant, aesthetically pleasing box.
Application in aquaristics
The RO3 filter has been developed with aquaristics in mind and supports the preparation of water with parameters important for many fish and plant species.
-
Lowering water conductivity – this is an important parameter in aquaristics. The set is intended for freshwater aquariums. For marine aquariums, the system can be expanded with a DEMI module.
-
Lowering pH – the average reduction is about 1–2 points, depending on the input water parameters.
-
Water softening – the osmotic membrane effectively removes calcium and magnesium compounds, reducing total water hardness to zero or close to zero dH, depending on the parameters of the filtered water.
The actual effects of lowering pH, conductivity, and hardness depend on the parameters of the feed water and the operating conditions of the system.
Filtration stages
1. WPL2 – linear polypropylene foam cartridge
This cartridge is responsible for filtering sand, silt, rust particles, and other solid contaminants. It is the first stage of protection for the entire water filtration system, limiting the passage of larger impurities to subsequent stages and helping protect the membrane.
Recommended replacement: at most every 6 months.
2. WWL2 – linear carbon cartridge
The carbon cartridge removes contaminants from the water such as chlorine, chlorine compounds, and organic contaminants. This stage improves the quality of the water fed to the membrane and supports longer, stable operation.
Recommended replacement: at most every 6 months.
3. 75 GPD osmotic membrane
The membrane is a set of semi-permeable thin-film membranes. Combined with pre-filtration using polypropylene fleece and activated carbon, it allows for obtaining very clean water. The membrane removes up to 99% of all compounds dissolved in water, as well as bacteria and viruses.
Estimated membrane lifespan: approximately 3–5 years.

-
Polish installation instructions
-
Water connection to choose from: 3/8”, 1/2”, 3/4” or shower connection
After purchase, the selected connection must be specified. If no connection is selected, the standard 1/2” connection is included. If the shower connection is chosen, the set does not include a brass valve, as its function is performed by the shower faucet.
Available connections
-
3/8” connection (approximately 15 mm)
-
1/2” connection (approximately 20 mm)
-
3/4” connection for washing machine or dishwasher (approximately 25 mm)
-
1/2” shower connection (approximately 20 mm)
If no connection is selected, the set will include the standard 1/2” connection.
Operation and use
Regular replacement of the pre-filters is crucial for maintaining high filtration efficiency and protecting the osmotic membrane. The WPL2 and WWL2 cartridges should be replaced at most every 6 months, while the lifespan of the 75 GPD membrane is usually about 3–5 years.
The performance of the reverse osmosis system is affected, among other things, by the pressure and temperature of the feed water. Variable operating conditions also affect the ratio of pure water to reject water and the final parameters of the treated water.
Additional important information
- Elegant, aesthetically pleasing box.
- 3/4" connection (washing machine/dishwasher), (approximately 25 mm)
