myAQUA 1900 - osmosis system

The Arka myAQUA 1900® is a highly efficient reverse osmosis system specially developed for use in saltwater and freshwater aquariums. With an impressive daily output of up to 1900 liters of reverse osmosis water and a flow rate of approximately 1.3 liters per minute, it reliably ensures crystal-clear, pollutant-free water – the optimal basis for a healthy aquarium.

Thanks to a four-stage filtration system, the Arka myAQUA 1900® reliably removes up to 99% of all pollutants contained in tap water, including salts, heavy metals, nitrate, phosphate, pesticides, herbicides, drug residues, bacteria, germs, and other contaminants. The system completely avoids chemical additives and relies exclusively on natural filter materials – for environmentally friendly and safe water treatment.

Integrated filtration system overview
Fine filter: Effectively removes coarse particles such as sand, rust, and suspended matter.
Carbon filter C1: Eliminates odors, chlorine, discoloration, and organic residues.
Carbon filter C2: Enhances the effectiveness of C1 and reliably filters pesticide and drug residues.
High-performance membrane: Removes up to 99% of all dissolved pollutants and bacteria.

As an efficient addition, the fourth filter stage (carbon filter C2) can also be replaced with a highly effective resin filter. This removes even the finest residues of silicate, nitrate or other inorganic substances.

Efficient & Sustainable
With a water yield of approximately 1:1 (osmosis water:wastewater), the system is particularly resource-efficient, making it one of the most efficient models on the market. The durable booster pump ensures a consistently high flow rate even at low line pressure – for optimal filtration results with low power consumption of only 70 W in operation (1-2 W in standby).

User-Friendly & Safe
Installation is particularly easy thanks to the extensive accessories and included wall bracket – connection to standard water pipes is a breeze. The system also features a built-in protection function: After 12 hours of continuous operation, production automatically shuts off to protect the device. The operating LEDs indicate the status at a glance.
