The Growmax Super Grow 800 Filter is a 2 stage water filter that delivers approx. 800 litres per hour of chlorine free, low contaminant water. These filters do not have a reverse osmosis membrane so do not lower the EC of the water, but they do filter out allot of the unwanted elements you find in UK tap water.

Removes up-to 95% of potentially harmful contaminants
No electricity or minimum pressure required
Effective for around 27,000L, or around 6 months
Ready to use, easy installation

Using eco-friendly coconut fibres with increased absorption capacity, the system effectively removes up to 95% of:

Chlorine, salts, heavy metals, chloramines, nitrates, nitrites. Sediment; dirt, rust, oxidation. Herbicides, pesticides, volatile organic contaminants (VOCs - chemical contaminants, benzenes, toluene, oils, THMs, detergents and PCBs).

For systems that are using beneficial bacteria and micro-organisms chlorine should be avoided - these filters make sure that all of the water you deliver to your root zone is not going to cause any problems.

The filters on the Super Grow 800 last for around 27,000 litres or 6 months. We list the replacements in the dropdown above, along with a replacement membrane - this will need changing approx. every 9 months. Using 6mm piping and fittings, the Growmax Super Grow 800 Water Filter Filter outputs up-to 20,000L/day, however if this does not quite meet your needs, please check out ourfull range of water filtration options here.
