The myAqua Reverse osmosis system 1.900 from ARKA quickly and effectively filters up to 99 % of salts, bacteria and pollutants, such as nitrate, phosphate and heavy metals, from tap water. This completely purifies all tap water and provides the basis for ideal aquarium water.
myAqua achieves a water yield of up to 1:1 and contains only natural filter materials, without chemical additives. Four different filters are used for optimal effectiveness. The filtration starts with a fine filter that removes suspended matter. This is followed by the first carbon filter. This removes odours, discolouration, chlorine and other chemical components from the water. Now the tap water is passed through a filter membrane, which absorbs 99% of all pollutants, salts, pesticides, heavy metals and bacteria. Finally, the water enters a second carbon filter, which acts as an after-filter for final purification. A separately available resin filter can be used for filtering the finest residues of silicate, nitrate and other dissolved organic and inorganic substances. For reliable filtration, a change of media is indicated via LED and sound signal and the filters can be easily unscrewed from the anchorage on the osmosis system. The water tap supplied for the filtered osmosis water can be installed on any standard sink. An installation set is included in the scope of delivery.
