Its natural finish and polyglass construction make it a clean, corrosion-resistant choice for holding softening resin, carbon, calcite, or other treatment media in a footprint that disappears into a cabinet or under a counter.\u003c\/p\u003e\u003ch3\u003ePolyglass construction\u003c\/h3\u003e\u003cp\u003ePolyglass—fiberglass-reinforced—mineral tanks are the industry standard for very good reason. They resist corrosion from the inside, where media and water chemistry would steadily attack steel, and from the outside, where the humidity of a mechanical room takes its toll over the years. The seamless inner liner won't rust or flake into the water it holds, and the tank handles the working pressures of residential treatment systems with ease. The translucent natural shell is a quiet practical advantage too: you can often gauge the media level through the wall without opening the tank. At just over 4 lbs empty, this 6\" x 18\" vessel is light enough for one person to handle and position comfortably during installation or service.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e6\" diameter x 18\" height compact format\u003c\/li\u003e\n\u003cli\u003eNatural-finish polyglass (fiberglass-reinforced) construction\u003c\/li\u003e\n\u003cli\u003eCorrosion-resistant inside and out\u003c\/li\u003e\n\u003cli\u003eHolds softening resin, carbon, or specialty media\u003c\/li\u003e\n\u003cli\u003eApproximately 4.2 lb empty weight\u003c\/li\u003e\n\u003cli\u003eGenuine Pentair mineral tank (alt. PT0618-A)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThis small-diameter tank suits a wide range of jobs: a point-of-use carbon polishing filter, a compact softener for a tight space, a dechlorination cartridge ahead of an appliance, or a custom specialty-media application targeting a specific contaminant. Because it's a genuine Pentair tank, it pairs predictably with the standard control valves and distributors sized for its opening, so it drops into a build without surprises. When loading media, cap the distributor tube to keep resin or carbon out of the riser, and leave appropriate freeboard above the bed so it can expand during backwash. Whether you're assembling a new compact system, replacing an aging tank, or putting together a specialty filter for a particular water problem, the 6\" x 18\" polyglass mineral tank gives you a durable, properly engineered vessel in a footprint that fits where bigger tanks can't. Add the appropriate valve, distributor, and media to complete a reliable small-scale treatment system.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":45668848009269,"sku":"PT0618-A","price":133.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/4950\/2261\/files\/pt0618-n_fc6c2279-bec9-4970-971a-b3f55caa9062.jpg?v=1782682391","url":"https:\/\/watersoftenerplus.com\/en-as\/products\/min-tnk-6x18-natural-polyglass","provider":"Water Softener Plus","version":"1.0","type":"link"}
