Product Description

The Aqua Grow Neptune 480 water filter system for hydroponics and gardening is a high performance system which removes chlorine, sediment, dirt, rust, oxidation herbicides and pesticides and volatile organic contaminants (chemical contaminants, benzenes, toluene, oils, THM’s, detergents, PCB’s).

The removal of these unwanted contaminants provides a wide range of benefits, including:

  • Faster growing plants and gardens.
  • Healthier fruits and vegetables.
  • Strengthens plant roots.
  • Protects soils, great for organics.

While the Neptune 480 doesn't feature any fancy branding like other systems on the market, it does feature high quality components from leading manufacturers such as John Guest and Pentek.

The Pentek carbon block filter is rated a 5 microns with a capacity of 45,400 litres*, with most other systems on the market utilising a filter rated at 10 microns with a 27,000 litre capacity.

System comes complete with everything required to connect to a standard garden tap (3/4" BSP) and housing spanner for easy filter changes.
