ARKA myAqua 400® - Reverse Osmosis System

ARKA myAQUA® 400 - your reverse osmosis system for crystal-clear aquarium water

The ARKA myAQUA® 400 is a powerful reverse osmosis system that has been specially developed for the requirements of freshwater and saltwater aquariums. It produces up to 400 L of osmosis water per day and effectively filters out up to 99% of pollutants, salts, bacteria, pesticides, heavy metals and more from tap water without any chemical additives.

The perfect water for your aquarium
Whether you've got delicate corals, tropical fish or plant-rich aquascapes in your aquarium, with the ARKA myAQUA® 400 you can ensure the best water quality for your needs. Plus, thanks to the natural filter materials and a high water yield of around 1:1 (osmosis water to waste water), you'll be protecting both your aquarium inhabitants and the environment.

Multi-stage filter system - for maximum purity
The ARKA myAQUA® 400 works with a four-stage high-performance filter system:

1. Fine filter: Effectively filters out coarse particles such as rust, sand and suspended matter from water.
2. Carbon filter 1: Filters odours, discolouration, chlorine, pesticides, herbicides and drug residues.
3. Membrane: Filters out up to 99% of pollutants, salts, pesticides, heavy metals and bacteria.
4. Carbon filter 2: Serves as a secondary filter and ensures the final filtering out of pollutants in combination with the carbon filter 1.

Safe, efficient and easy to use
The automatic switch-off function pauses the system if the inlet pressure falls below 0.8 bar, ensuring maximum operational safety. As soon as the pressure is adequate again, it continues to run as normal.

With the included accessories, the ARKA myAQUA® 400 can be easily connected to your household water pipe without any complicated installation.
