ARKA myAqua1900 reverse osmosis system uses the power of water pressure and filters up to 99 percent of salts, bacteria and contaminants such as nitrite or phosphate and heavy metals from conventional tap water. The ratio of osmosis water to residual water is only 1:1-1.5. This is how effectively the water is treated to create a safe feel-good atmosphere for marine and freshwater inhabitants.
The system works without chemical additives - it works via water pressure and natural filter materials, without chemical additives. This means that the retention rate is very high.
- Filter capacity: up to 1900 liters / day
- Osmosis water to residual water: yield approx. 1:1 – 1.5
- Working pressure: 1 to 4 bar
- Temperature: 5 to 38 degrees
- Salt retention capacity: 98% – 99%
The following replacement intervals apply to the system components carbon and fine filter (cartridge) and the membrane filter:
- Membrane filter: 12 – 24 months from commissioning
- Fine filter: 6 – 12 months from commissioning
- Carbon filter C1: 6 – 12 months from commissioning
- Carbon filter C2: 6 – 12 months from commissioning
Tip: Filters are consumables and must be replaced regularly! To ensure that your animals can always enjoy consistently high water quality, we recommend keeping them in stock. All three system components (carbon, fine and membrane filters) are available separately.
ARKA myAQUA® 1900 quickly and effectively filters up to 99% of salts, bacteria and contaminants (such as nitrate, phosphate and heavy metals) from tap water, making it safe for use in any salt or freshwater aquarium.
ARKA myAQUA® 1900 achieves a water yield of up to 1:1 and contains only natural filter materials without chemical additives.
ARKA myAQUA® 1900 can be connected to commercially available domestic water pipes thanks to the included accessories.
Note: built-in security feature
Our ARKA myAQUA® 1900 has an automatic shut-off function. It interrupts the production of osmosis water after 12 hours of continuous use. The LEDs then light up red. If you want to continue producing osmosis water, briefly disconnect the device from the power supply. The system will then continue to operate normally.
1x faucet
1x 150 cm hose
1x 300 cm hose
1x T-piece including valve
1x wall mount
1x TDS measuring device
1x waste water clamp
1x water connection (3/4 "-1/4")
