ADA NA Water RO

Although tap water is clean water that has been filtered and sanitized with chlorine, the impurities in the tap water, such as residual chlorine and metal ions, are problematic for keeping aquatic organisms in it. NA Water is a water purification system that removes the residual chlorine and other impurities quickly. It produces purified water suitable for keeping the aquatic organisms. Anyone can make safe water for aquarium by connecting water outlet and hose.

○ Easy to use even for the first time.
Since NA Water has filters loaded at the time of shipment, it can be used easily by simply connecting it to a water supply with a hose (please prepare a pressure-resistant hose for water supply separately).

○ Two types of filters are included.
There is a possibility that tap water contains impurities such as iron rust, harmful substances such as chlorine residue, and germs. Two types of filters, Pre-Filter PP5 and Carbon Filter HD30, remove impurities and harmful substances efficiently.

■ Effects of NA Water

To use Nature Aquarium water purifying system NA Water, connect it to a tap water faucet. NA Water comes with Pre Filter PP5 and Carbon Filter HD30 as the default. With these filters, NA water eliminates impurities in water such as iron rust and at the same time, removes residual chlorine.

Carbon Filter HD30 that removes residual chlorine can later be replaced with Carbon Filter HD300 having a longer-lasting absorption effect. Since the tap water passed through NA Water is free from residual chlorine, there is no need to apply Aqua Conditioner Chlor-Off during water change as long as NA Water is used.

NA Water is usually installed for the purpose of eliminating residual chlorine.

Note :

* The Cation Filter (optional, to be purchased seperately )turns tap water into soft water suitable for growing aquatic plants by lowering the total hardness (TH)of tap water.

On top of this function, the water softening effect can now be easily added by using the new Cation Filter as a replacement cartridge filter.

Note that the Cation Filter is intended for lowering the total hardness of water only and it is not for producing pure water. As pure water is not required for Nature Aquarium, user-friendly Cation Filter was adopted for the new NA Water.

Features of Cation Filter

The total hardness level of tap water varies by area. In Japan, the tap water in urban areas of Kanto and Kansai regions tends to have high total hardness. Firstly, measure the total hardness of the tap water to be used for water change with Pack Checker TH. If the measured value exceeds 100mg/ℓ, the tap water of the area is hard water and thus the use NA Water and Cation Filter is recommended. The

Cation Filter can turn approximately 1,000ℓ of tap water with TH100-200mg/ℓ into soft water with below TH50mg/ℓ. Check for its water softening effect using PACK CHECKER TH (Total Hardness).

When the Cation filter is no longer effective, replace it with a new one or carry out the regeneration of cation exchange resin following the procedures outlined below.

[Cation filter regeneration procedures]

① Remove Cation filter from NA Water.

② Dissolve 100g of refined salt (over 99.5% sodium chloride) into 1ℓ of tap water to make approximately 10% saline solution.

③ Place Cation filter upright (with the packing side up) in a place such as kitchen sink and slowly pour saline solution into the CATION FILTER. Be careful not to allow the saline solution to overflow from the opening on the filter top (saline solution will flow out from the hole on the filter bottom).

④ Once 1ℓ of saline solution has run through the CATION FILTER, pour tap water from the opening on the filter top. When sufficient amount of tap water has run through the filter until no saline solution flows out from the bottom hole, the regeneration of CATION FILTER is completed.

*Cation Filter can be used repeatedly by carrying out regeneration. If sufficient water softening effect is not obtained even after regeneration, replace with a new Cation filter.

Operating Instructions of CATION FILTER

①Remove Clear housing on both inlet (IN) and outlet (OUT) sides.

②Insert Carbon filter HD30 into the Clear housing on the inlet (IN) side and Cation filter into the Clear housing on the outlet (OUT) side (Photo A). Do not use Pre filter PP5.  (*The Cation filter has orientation. Be sure to insert the Cation filter in the arrow direction and with the packing side up.)

③Make sure that two O-rings are placed in each Clear housing and then install Clear housings to NA-WATER (Photo B).
