A loaded sediment filter slowly chokes the flow, and a spent carbon block lets chlorine through to the membranes, where it does permanent damage. The first signs are slower production and creeping EC in the water you collect — by then the membranes have been exposed for weeks. Replacing the full set on schedule protects the most expensive part of the system and keeps feed water clean for the nutrient tank.\u003c\/p\u003e\n\u003ch3\u003eHow to Use\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShut off the supply\u003c\/strong\u003e and release the pressure before opening any housing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnscrew the three housings\u003c\/strong\u003e, remove the old cartridges and rinse the bowls\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit the sediment filter in the first housing\u003c\/strong\u003e and a carbon block in each of the next two; check the O-rings are seated before retightening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRun the first water to waste\u003c\/strong\u003e for a few minutes before filling a reservoir\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplace the set\u003c\/strong\u003e after about \u003cstrong\u003e8,000 litres\u003c\/strong\u003e of produced water, and the carbon at least every 6 months\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"hcs-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e GrowMax Mega Grow 1000 reverse osmosis system\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContents:\u003c\/strong\u003e 1 x 5 micron sediment filter, 2 x green carbon block filters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCartridge size:\u003c\/strong\u003e 10 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemoves:\u003c\/strong\u003e chlorine and organic contaminants; sediment above 5 microns\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter pack life:\u003c\/strong\u003e about 8,000 litres of produced water; carbon at least every 6 months\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaker reference:\u003c\/strong\u003e GMWPACKMEGA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cdiv class=\"hcs-faq\"\u003e\n\u003cdetails style=\"border:1px solid #e6e6e6;border-radius:8px;padding:12px 16px;margin:0 0 8px;\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600;\"\u003eHow is this different from the GrowMax 10 Inch Replacement Filter Pack?\u003c\/summary\u003e\u003cp style=\"margin:10px 0 0;\"\u003eThe 10 Inch pack holds one sediment filter and one carbon block.
