There are four connections on the front. You can connect an additional tap and a water tank here; an automatic shut-off is already integrated. Simply insert the hose – that's it. The automatic shut-off is built in. Installation really couldn't be easier.

This reverse osmosis system is suitable for water treatment in marine and freshwater aquariums and for travel!

Output: up to 200 liters per day (at 22°C water temperature)

The most modern and environmentally friendly method of water treatment!

Water is one of the most important elements for the life of humans, animals, and plants on our planet! But it is often contaminated by pollutants, and these pollutants can cause health problems.

Reverse osmosis systems offer an affordable and effective way to produce very clean water! In reverse osmosis, the raw water is forced against a membrane; only pure water (permeate) can pass through the membrane, while the contaminants are removed with the residual water (concentrate).

The quality and quantity of the reverse osmosis water depends on the pressure and temperature of the raw water.

Most commercially available water treatment systems that operate on the basis of ion exchange exchange hardness-causing ions (e.g., calcium) for other ions (e.g., sodium). This can lead to a shift in the ion ratio, which can have unpredictable consequences in the aquarium. Such systems require regular regeneration with chemicals!

Reverse osmosis is a natural process that safely removes dissolved salts and pollutants from water using physical means!

Scope of delivery / Description:

- Membrane housing (pressure-resistant), including bracket, wall mounting possible

- TFC osmosis membrane made of polyamide/polysulfone, original membrane 100 GPD

- Inline sediment filter 10" x 2", and inline activated carbon filter 10" x 2"


The total salt content and therefore the conductivity of the reverse osmosis water depends on the quality of the tap water (raw water)!
