AQUA PRO 3000 Reverse Osmosis Unit 3000 US Gallon Per Day Rated RO System (2500 UK gallons a day)

The AQUA PRO 3000 Incorporating 3 x 1000 US GPD genuine USA produced Thin Film Composite Reverse Osmosis Membranes, This system will produce a large amount of pure water whatever your needs.

This high quality RO System incorporates 2 x 20 inch Pre Filter, 3 x Stainless Steel housings, a Manual Restrictor Valve and optional Auto Flush bypass kit which can be supplied with transformer and digital timer, also an optional Commercial Inline Dual TDS Monitor and Polyprop mounting boards in black as shown below.


This unit is up and running in our fish house and is producing 1000 gallons a day on a 50/50 ratio, the first of its kind in the UK!

We have a mains water supply with a TDS of 385, this unit gives product water with a TDS of 9 and a waste TDS of around 700 !

The AQUA PRO 3000 5 stages of filtration are:

  • 5 Micron Sediment Filter Made From 100% Pure Polypropylene Fibres, Removes Dirt, Sand and Rust.
  • Carbon Block Filter, Composed of High - Performance Carbon, Removes Free Chlorine, Odour, Organic Contaminants, Trihalomethanes, Pesticides, Volatile Organic Chemicals and 99.95% of Giardia and Cryptosporidium Cysts.
  • 3 x 1000 US Gallon per day High Rejection Thin Film Composite Reverse Osmosis Membranes.


AQUA PRO 3000 Features:

  • 2 x 20 inch Pre filter
  • Pressure Gauge
  • Inline TDS Meter from HM Digital
  • Pre Filter Housing Wrench
  • Sturdy polyprop mounting board
  • Hosebarb connections supplied to allow connection to 1/2 inch Food Grade Pipe
  • 20 times a day Auto flush valve used to periodically flush the membranes
  • Digital Timer
  • Digital Timer Transformer

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 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.
