GrowMax Water Deionization Filter Cartridge 10" for Maxquarium 000 ppm and DI Kit 10"

The GrowMax deionization filter cartridge is the final filtration stage for those who require absolutely pure water . It is used specifically in combination with reverse osmosis systems – for example, the GrowMax Maxquarium 000 ppm or GrowMax DI Kit 10" .

Guaranteed purest water with 0 ppm

Thanks to a high-quality mixed-bed resin, the DI cartridge reliably removes the last traces of dissolved salts, minerals, and ions – even after reverse osmosis. The result is an electrical conductivity (EC) of 0 ppm , which is required in aquariums, for sensitive plants, or in the production of nutrient solutions for compost tea, clones, or seedlings .

Easy application & maintenance

The DI cartridge fits into any standard 10" filter housing and can be easily replaced as the EC value increases. A TDS meter (not included) indicates when a change is necessary.
