How does the Pro 3000 System work?

This Reverse Osmosis Filter System does a great job of removing chemicals and contaminants, as well as 95% of mineral salts which cause the hardness of the local water. The water this system produces is perfect for use with humidifiers and misting equipment, as it doesn’t leave any powdery residue behind and thereby preserves the well-being of your equipment.

Using reverse osmosis water has three key benefits:

  1. It removes the chlorine and lets the soil biosphere flourish, which is especially useful if you use bacterial or microbial additives, the friendly bacteria to which growers are increasingly turning.

It provides a stable pH. Reverse osmosis water has a pH of around 6.5, which is a good starting point for most plants.
  3. It allows for more accurate control of fertilisation. By getting rid of the background EC of your local tap water, you’ll be delivering your plants a much more balanced nutrient solution.

This product’s filters last about 25,000 litres or six months, whichever is the soonest. The replacement membrane will also need changing approximately every nine months or so.

How do I use this RO System?

The Pro 3000 RO Filter System is easy to use, and the assembly is intuitive.

Firstly you should install the cold water supply valve and the drain adapter. You should then make the necessary tubing connections and install the Reserve Osmosis assembly. That’s all there is to it. You only need to put this into operation to make it start to work.
