ARKA myAQUA® 400 quickly and effectively filters up to 99% of salts, bacteria and pollutants (such as nitrate, phosphate and heavy metals) from tap water, making it safe for use in any saltwater or freshwater aquarium.
ARKA myAQUA® 400 achieves a water yield of up to 1:1 and contains only natural filter materials without chemical additives.
ARKA myAQUA® 400 can be connected to commercially available household water pipes thanks to the accessories supplied.
Note: Built-in protection function
Our ARKA myAQUA® 400 has an automatic switch-off function. It interrupts osmosis water production if the applied pressure falls below 0.8 bar. If you wish to continue osmosis water production, ensure that the inlet pressure is sufficient. The system will then resume normal operation.
