Description
Produces up to 500 litres a day, around 20 litres an hour, of ultra pure water. Built to get you to 000 PPM, so it suits aquariums as well as growing.
What it does
- Gets you to an EC of 000 PPM with the DI stage included
- Removes up to 95% of mineral salts and heavy metals, and the DI filter takes out the rest
- Removes up to 99% of chlorine
- Filters sediment above 5 microns
- Steadier pH and better nutrient performance
- Protects the beneficial microbes in your substrate
- Keeps algae down and pH stable in an aquarium
Removes or reduces mineral salts, heavy metals, chloramines, nitrates, nitrites, sediment, sand, oxides, herbicides, pesticides and volatile organic pollutants including benzene, oils, trihalomethanes, detergents and PCBs.
On hard water? Check your TDS first
GrowMax rate their RO systems for up to 1000 TDS at 60 PSI. Above that you need the Booster Pump Kit to push pressure past 60 PSI, which takes the unit to a maximum of 1500 TDS. The higher your incoming TDS, the lower the output, whatever the pressure. Most UK tap water sits well inside 1000, but boreholes and the harder areas do not.
Filters and when to change them
| 10" Filter Pack | Every 4,000 litres |
| RO Membrane 150 GPD | When EC rises or output drops |
| 10" De-Ionization Filter | When EC rises or output drops |
Low water pressure?
This unit needs 40 PSI minimum. If yours is under, the Booster Pump Kit is the one specified for it. If you have not bought a unit yet, the Max Pump 700 has a pump built in and needs no kit.
