Description
Restore Clean Water to Your Power Grow 500
The replacement membrane for the GrowMax Power Grow 500 RO filter, and the component that does the actual separating. It removes or reduces up to 95% of all salts and heavy metals, taking hard mains water down to a clean, low-EC base. Membranes wear with use rather than time alone, and the harder your water, the more often this will need replacing. A membrane past its best shows up as slower output, creeping EC and feed that no longer matches the chart. Fitting is a straightforward swap into the existing housing.
Key Benefits
- Up to 95% removal of salts and heavy metals, restoring original performance
- Direct replacement for the Power Grow 500 with no modification needed
- Consistent low starting EC so nutrient ratios stay under your control
- Protects your feed programme from the drift a tired membrane causes
- Extends the life of the unit, keeping a working filter in service
When Hard Water Undermines the Feed Chart
Background calcium and magnesium in UK tap water take up nutrient headroom before you start, and the effects are familiar: lockout, poor nutrient uptake, slow growth and results that never match the schedule you are following. Rejection falls away gradually enough that most growers do not notice until the plants do. Replacing the membrane puts your starting water back to a known quantity.
How to Use
- Turn off and depressurise the supply before opening the housing
- Insert the replacement in the same orientation, seals to the inlet
- Reseal and flush to waste before using the water on plants
- Replace more frequently in hard water areas, where loading is faster
- Keep the pre-carbon stage fresh, as chlorine shortens membrane life
- Monitor output EC as your guide to the next change
