Membranes are a consumable: as they load with dissolved solids, output slows and rejection drifts, so a tired membrane quietly costs you the clean water you bought the system for. Swapping it on schedule restores flow rate and rejection.\u003c\/p\u003e\u003ch3\u003eKey Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUp to 95% removal\u003c\/strong\u003e of mineral salts and heavy metals for a clean blank canvas\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh flow 150 GPD\u003c\/strong\u003e rating restores original throughput to a slowing system\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect fit\u003c\/strong\u003e for Power Grow 500, Mega Grow 1000 and Maxquarium 000 PPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLower, predictable starting EC\u003c\/strong\u003e so feed charts behave as intended\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSimple maintenance part\u003c\/strong\u003e that keeps an existing RO unit in service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eHard Water, Rising EC and Poor Nutrient Uptake\u003c\/h3\u003e\u003cp\u003eTap water across much of the UK arrives loaded with calcium and magnesium before you add a millilitre of feed.
