This reverse osmosis system combines effective mechanical and carbon filtration, an efficient Pentair Water 75 GPD osmosis membrane, and a DI demineralization stage with MB400 resin, delivering water with zero TDS. It is a premium-grade solution for marine and freshwater aquariums, ATO top-offs and salt mixing, wherever full control of water parameters and a reliable water filtration system are essential.

Professional premium-class RO/DI aquarium filter

AQUAVITA RO4 DEMI PRO is an original, fully professional aquarium filter designed to produce fully demineralized water (RO/DI). The use of high-quality components ensures the system meets the expectations of users who need stable, clean water for tanks requiring precise parameters.

The unit is equipped with a Pentair Water 75 GPD (USA) osmosis membrane, high-quality AQUAVITA BPA FREE filter cartridges, and a serviceable DI cartridge with MB400 resin. This configuration makes it a PRO solution for aquarists expecting absolute water purity and repeatable results during everyday use.

The system is especially recommended for marine (reef) and freshwater aquariums, wherever full control of water parameters is required: zero TDS, low conductivity, low pH, and an almost zero content of nitrogen compounds.

Why choose AQUAVITA RO4 DEMI PRO?

RO4 system (RO + DI) – ideal water even for the most demanding tanks
increased efficiency thanks to 10-inch housings
front panel with external connections – convenient installation and maintenance
BPA FREE, PHALATE FREE components
removes up to 99% of all contaminants
ideal for water changes, ATO top-offs and salt mixing

This is a complete reverse osmosis aquarium filter that combines ease of use with high water treatment efficiency. Thanks to its well-thought-out design, it is suitable both for regular home use and where very high water quality is required for specialized applications.

Advanced filtration stages

1. AQUAVITA FCPS20 sediment filter – 20 µm

A high-grade polypropylene fleece cartridge provides the first stage of water purification and protects the subsequent stages of the system.

removes sand, silt, rust and mechanical sediment
very high contaminant absorption capacity
protects the subsequent filtration stages
certified by PZH, TÜV, BPA FREE, PHALATE FREE

2. AQUAVITA FCCBL10 block carbon filter

A professional sintered activated carbon cartridge is responsible for reducing chemical contaminants and protecting the osmosis membrane.

removes 98–99% of free chlorine
eliminates chlorinated solvents
reduces pesticides, phenols, benzene and organic compounds
improves water smell and quality
is an essential element of osmosis membrane protection
certifications: PZH, TÜV, BPA FREE, PHALATE FREE

3. DI demineralizing cartridge – MB400 Purolite resin

A professional, ready-to-use blend of anion and cation exchange resin provides the final refinement of water quality after the RO stage.

removes residual contaminants after RO
ensures zero TDS
serviceable cartridge – can be refilled
fits standard 10” housings
used in both aquaristics and laboratory installations

4. Pentair Water TLC-75 osmosis membrane – 75 GPD (USA)

A premium semipermeable membrane is the key element of the reverse osmosis process and is responsible for deep water purification.

filtration efficiency 96–99%
removes salts, heavy metals, organic and inorganic compounds
retains particles down to 0.01 micron
capacity: up to 270 l/day

The capacity of up to 270 l/day applies when proper feed water parameters are maintained. In practice, actual water production depends, among other things, on pressure, temperature and the quality of the incoming water.

Benefits in everyday use

This type of RO/DI system is chosen by users who do not want to base aquarium health on variable tap water parameters. The filtered water can be used for water changes, automatic ATO top-offs and saltwater preparation, and its very high purity helps stabilize conditions in the tank.

Also noteworthy is the convenient operation. The front panel with external connections simplifies installation and maintenance, while the use of standard 10-inch housings makes it easier to select consumables and perform routine system upkeep.

Set includes

complete AQUAVITA RO4 system
Pentair Water 75 GPD (USA) membrane
FCPS20 AQUAVITA sediment cartridge
FCCBL10 AQUAVITA carbon cartridge
MB400 Purolite DI cartridge (serviceable)
drain clamp
waste water restrictor
water connection 1/2", 3/8" or 3/4"
5 meters of tubing
complete installation accessories

Application

marine aquariums (reef, SPS, LPS)
freshwater aquariums
automatic top-offs (ATO)
salt mixing
laboratories and cosmetics
steam irons

To maintain high filtration efficiency and safe membrane operation, the condition of the pre-filters should be checked regularly and they should be replaced on time. Effective chlorine reduction before the RO stage is particularly important, as it directly affects the service life of the osmosis membrane.

FAQ

Is AQUAVITA RO4 DEMI PRO suitable for a marine aquarium?

Yes. The system was created for demanding applications, so it works very well in marine aquariums, including reef, SPS and LPS. Thanks to the RO/DI stage, it provides water with zero TDS, suitable for water changes, top-offs and salt mixing.

Can AQUAVITA RO4 DEMI PRO Aquarium Filter AC-OM-75 also be used in a freshwater aquarium?

Yes. The filter is also suitable for freshwater aquariums, especially when you want full control over the outgoing water parameters and want to build the target parameters yourself before adding it to the tank.

What does the RO4 system (RO + DI) mean?

RO4 refers to a system consisting of pre-filtration stages, a reverse osmosis membrane and final DI demineralization. The combination of RO and DI removes most contaminants and then captures the remaining traces after the membrane, producing water with zero TDS.

What contaminants does AQUAVITA RO4 DEMI PRO remove?

The system removes, among other things, sand, silt, rust and mechanical sediment, 98–99% of free chlorine, chlorinated solvents, pesticides, phenols, benzene and other organic compounds. The membrane also reduces salts, heavy metals, and organic and inorganic compounds, while the DI cartridge removes residual contaminants after RO.

Does the filter provide zero TDS water?

Yes, that is the purpose of using the DI stage with MB400 Purolite resin. The demineralizing cartridge removes residual contaminants after the RO stage and allows you to obtain water with zero TDS, especially valued in marine aquariums and other demanding applications.

What is the membrane capacity?

The Pentair Water TLC-75 membrane has a capacity of up to 270 l/day. The final amount of water obtained depends on the feed water parameters, especially pressure, temperature and the quality of the incoming water.

Can the DI cartridge be refilled?

Yes. The DI cartridge with MB400 resin is serviceable, which means it can be refilled. This is a practical solution that makes system operation and maintenance easier.

What is included in the installation kit?

The set includes the complete AQUAVITA RO4 system, Pentair Water 75 GPD membrane, FCPS20 sediment cartridge, FCCBL10 carbon cartridge, MB400 Purolite DI cartridge, drain clamp, waste water restrictor, water connection 1/2", 3/8" or 3/4", 5 meters of tubing and a full set of installation accessories.

What uses outside aquaristics can this system be used for?

Outside marine and freshwater aquariums, the system can be used for ATO top-offs, salt mixing, as well as in laboratories, cosmetics and for steam irons.
