It fouls slowly, and the first signs are a \u003cstrong\u003erising PPM reading\u003c\/strong\u003e on the product water and a tank that takes noticeably longer to fill. Left alone, that drift quietly changes the starting point of every nutrient mix you make, so an EC you have dialled in over months stops behaving. Swapping the membrane is the fix, and on a system running mains water it is normally a \u003cstrong\u003e6 to 18 month\u003c\/strong\u003e job. Always renew the \u003cstrong\u003eKDF85\/carbon pre-filter\u003c\/strong\u003e alongside it, because chlorine passing an exhausted pre-filter is what shortens a membrane's life in the first place.\u003c\/p\u003e\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e75 GPD (approx. 284 L\/day)\u003c\/strong\u003e high-rejection element, restoring the system's rated output\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e98-99% dissolved-solids rejection\u003c\/strong\u003e for a stable, repeatable low-PPM starting point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard 1812 format\u003c\/strong\u003e — drops straight into the MicRO 75 membrane housing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect replacement\u003c\/strong\u003e, no tools or modification needed beyond the housing cap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtects your EC control\u003c\/strong\u003e so nutrient strength means the same thing week to week\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHow to Use\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTurn off the feed water and release system pressure before opening the housing.\u003c\/li\u003e\n\u003cli\u003eUnscrew the membrane housing cap and withdraw the spent element.\u003c\/li\u003e\n\u003cli\u003eFit the new membrane with the \u003cstrong\u003edouble O-ring end first\u003c\/strong\u003e, seating it fully into the socket.\u003c\/li\u003e\n\u003cli\u003eRefit the cap, restore water and \u003cstrong\u003eflush to drain for 10-15 minutes\u003c\/strong\u003e before collecting any product water.\u003c\/li\u003e\n\u003cli\u003eRenew the \u003cstrong\u003eKDF85\/carbon pre-filter\u003c\/strong\u003e at the same time for the longest membrane life.\u003c\/li\u003e\n\u003cli\u003eCheck output PPM with a meter once flushed to confirm rejection has returned.\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\u003eType:\u003c\/strong\u003e Thin-film composite reverse osmosis membrane element\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated production:\u003c\/strong\u003e 75 GPD (approx. 284 L\/day)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRejection rate:\u003c\/strong\u003e 98-99% of dissolved solids\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e 1812 (approx. 1.8\" diameter x 12\" length)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Hydrologic MicRO 75 reverse osmosis system\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating pressure:\u003c\/strong\u003e 40-80 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService interval:\u003c\/strong\u003e typically 6-18 months, depending on feed water and pre-filter care\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Hydro-Logic","offers":[{"title":"Default Title","offer_id":53632113869066,"sku":"HYD-HYD2-002-01","price":29.98,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/hydrologic-micro-75-replacement-ro-membrane-1.webp?v=1788627973","url":"https:\/\/hydrocropshop.co.uk\/products\/hydrologic-micro-75-replacement-ro-membrane","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
