Purity on Tap is, today, the largest independent UK manufacturer of aquatic purification equipment.
In their Koi water gardening & Coldwater range they have a tremendous selection of purifiers to suit even the most demanding pond keepers needs.
The New Merlin™ Reverse Osmosis System by GE Infrastructure Water & Process Technologies has a revolutionary new design in reverse osmosis technology and provides up to 720 gallons of purified water per day without a tank.
Evolution Aqua in-line De-Ionisers purify tap water using a de-mineralising process called de-ionisation. The new De-Chlorinator from EA is a quick and simple method of filtering-out harmful chlorine and other impurities from tap water.
The water we drink is not fit for Koi by any means.
Mains water contains Chlorine and many hard metals, that are not healthy or productive for a healthy and balanced nitrogen cycle.
To have effective water purification it is best to allow for very slow flow rates. The longer the water takes to pass through the purifier, the greater the benefits of the purification system.
A flow rate of one to two gallons per minute should adequately remove any nasty impurities, and the water can safely be added directly into your filtration system or the pond.
