{"product_id":"velda-clear-control-pressure-filter-with-uv-c","title":"Velda Clear Control Pressure Filter with UV-C","description":"\u003cp\u003eContinuous filtration keeps your pond water clear and reduces the toxins that build up between cleans, while the built-in UV-C lamp breaks down green floating algae so clarity holds for longer. A six-position valve lets you backwash, drain the pond or dose medication without lifting the housing apart, and the pressure-rated build means the water can still gravity-feed a waterfall or stream once it leaves the filter. Two capacities are available, so check the sizing guidance to match one to your pond volume.\u003c\/p\u003e\u003ch2 class=\"h4\"\u003eOverview\u003c\/h2\u003e\u003cp\u003eThe Clear Control is a pressure filter built around a six-position valve, so backwashing, draining the pond or dosing the water with medication can all be done without opening the housing or disturbing the filter media inside. A UV-C lamp deals with green floating algae and germs before the water reaches the filter bed, and layered media inside handles coarse dirt, fine particles and biological breakdown of waste in one pass. Running it continuously helps keep the water clear and reduces the build-up of toxins that affect fish health. Because the housing is pressure-rated, you can also site the filter above pond level and still let gravity carry the water on to a fountain, waterfall or stream.\u003c\/p\u003e\u003ch2 class=\"h4\"\u003eKey benefits\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThe valve's six positions cover backwashing, draining, filtration, stopping the flow and winter storage, so routine maintenance doesn't mean opening the housing\u003c\/li\u003e\n\u003cli\u003eUV-C lamp breaks down green floating algae and neutralises germs before the water reaches the filter bed\u003c\/li\u003e\n\u003cli\u003eLayered media combines mechanical, chemical and biological filtration in a single pass\u003c\/li\u003e\n\u003cli\u003ePressure-rated housing lets you site the filter above pond level and still gravity-feed a waterfall, fountain or stream afterwards\u003c\/li\u003e\n\u003cli\u003eCompact housing designed to be straightforward to install and clean\u003c\/li\u003e\n\u003cli\u003eCan take an optional pond heater accessory if you want to manage water temperature through colder months\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2 class=\"h4\"\u003eChoosing your size\u003c\/h2\u003e\u003cp\u003eBoth models are built for different pond volumes rather than differing in how they work, using the same valve and filtration set-up.

Filtration is the normal running position. Backwash flushes debris out from under the grate if the flow has slowed, using a reverse flow through the media, and this position is for clearing the filter itself rather than for pond water. Pond drain empties the pond or clears the valve, using a hose connected to the waste outflow. Stop shuts off flow through the filter while you service the pump, without draining the housing. Bypass routes water around the media, which is what you'd use while dosing the pond with medication, though it needs rinsing once the treatment period ends. Winter releases pressure from the valve mechanism for safe off-season storage. Switch the pump off before moving the valve between positions.\u003c\/p\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum operating pressure\u003c\/td\u003e\n\u003ctd\u003e1.5 bar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFiltration stages\u003c\/td\u003e\n\u003ctd\u003eMechanical (Japanese mat), chemical (activated carbon), biological (lava grit)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUV-C lamp wattage\u003c\/td\u003e\n\u003ctd\u003e9W (Clear Control 25) \/ 18W (Clear Control 50)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended pond volume\u003c\/td\u003e\n\u003ctd\u003eUp to 10,000 litres (Clear Control 25) \/ Up to 20,000 litres (Clear Control 50)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eValve positions\u003c\/td\u003e\n\u003ctd\u003eBackwash, pond drain, filtration, stop, bypass, winter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptional heating element\u003c\/td\u003e\n\u003ctd\u003eCompatible with a 300W Velda pond heater, sold separately\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"AquaticsHub","offers":[{"title":"25 + UV-C 9W","offer_id":57611633623413,"sku":null,"price":199.66,"currency_code":"GBP","in_stock":true},{"title":"50 + UV-C 18W - Unavailable","offer_id":57611633656181,"sku":null,"price":273.58,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/0610\/4949\/files\/25_uv-c_9w_1.png?v=1790480760","url":"https:\/\/aquaticshub.co.uk\/products\/velda-clear-control-pressure-filter-with-uv-c","provider":"AquaticsHub","version":"1.0","type":"link"}
