  • 3 x 100 US Gallon per day High Rejection Thin Film Composite Reverse Osmosis Membranes.

We strongly recommend that if you're mains water is via a water meter you will require a booster pump as the water meter reduces water pressure, please note this will greatly reduce wastage.

By using a 'Reverse-Osmosis' (R/O) plant, your mains water can be completely stripped of all minerals and contaminants, essentially producing pure H2O, or distilled water.

This R O water will usually have a TDS of perhaps 11ppm. Most of that 11ppm figure would actually be Carbon Dioxide, which makes the water acidic, but will quickly gas off, leaving you with a pH of around 7.

R/O plant water on its own is very dangerous for aquatic life, as it has absolutely no pH stability, and no mineral content. But, when mixed back in with dechlorinated untreated mains water, you can make the perfect water, which can give you superb results!

How I can achieve my 'ideal' water

Lets say your mains water currently has a TDS level of 335ppm. Contained within that reading is the KH, which runs at 11dH (190ppm). As far as growth and koi development are concerned, not really that good for your koi.

But, with an R O system that produces water with a near zero TDS, you can mix this water
with dechlorinated untreated mains water at a ratio of lets say 75% R O water, and 25% mains water, which results in a TDS of just 84ppm, and a KH of 2.75dH, which is more like it.

This may sound complicated, but provided that you know the KH value and TDS of your mains water before you mix it with R/O water, you can use the TDS meter to determine the KH value of your mixed water. In this case, if the mixed water TDS level rises above 84ppm, just reduce the flow of mains water a little, and if it's too low, then the flow is increased.

Running the above KH reading is perfectly safe if you carefully watch and make regular notes of your pond KH level. Obviously, if the KH depletes below the desired level, you will have to either change more water, or add a 'harder' mix of water.

Please note that Reverse Osmosis water contains no minerals, and hence is very
unstable. It is dangerous to use R/O water without mixing it with mains water.
