At higher flow rates the unit acts as a clarifier, killing suspended green-water algae. Slow the flow through the same unit and the longer exposure sterilizes, also affecting some bacteria and parasites. Most pond installations run in clarifier mode for green-water control.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill a UV clarifier kill string algae?\u003c\/strong\u003e\u003cbr\u003eNo. UV only affects the single-cell algae suspended in the water passing through the unit. String algae attached to rocks and liner needs the phosphate-binding and beneficial-bacteria approach in our \u003ca href=\"https:\/\/fountaindepot.com\/collections\/algaecides\"\u003ealgae-control collection\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use a pond UV sterilizer on an aquarium?\u003c\/strong\u003e\u003cbr\u003eInline UV units can be plumbed into large aquarium or quarantine systems, provided the flow rate through the unit matches the manufacturer's rating for the wattage. For typical home aquariums, a purpose-built aquarium UV is usually the better fit — contact us and we'll tell you honestly which is right.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhen should I run a UV clarifier in Canada?\u003c\/strong\u003e\u003cbr\u003eGreen water peaks with sunlight and warmth — run the UV from spring startup through fall. Remove and store the unit before freeze-up, and replace the bulb each season, since UV output drops well before the bulb visibly fails.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo UV clarifiers harm fish or beneficial bacteria?\u003c\/strong\u003e\u003cbr\u003eUV treats only the water passing through the sealed chamber, so fish are unaffected. The beneficial bacteria colonized on your filter media and pond surfaces are also unaffected; only free-floating microorganisms in the water column are exposed.\u003c\/p\u003e\n\u003cp\u003eOrders ship across Canada from stock, typically arriving in 3 to 10 business days depending on province.\u003c\/p\u003e","products":[{"product_id":"aquascape-ultraklean-pressurized-biological-pond-filter","title":"Aquascape UltraKlean Pressurized Biological Pond Filter","description":"\u003cp\u003eAquascape UltraKlean Pond Filter includes high-output ultraviolet clarifier and integrated filtration.\u003c\/p\u003e","brand":"Aquascape","offers":[{"title":"Default Title","offer_id":45393065476156,"sku":null,"price":479.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0696\/8675\/5388\/files\/UltraKlean_2000_Pond_Filter_-_Photo_2_-_Edited_1__55623.1671570952__93989.1674765445.png?v=1778592726"},{"product_id":"ultraklear-uv-clarifier","title":"UltraKlear UV Clarifier","description":"\u003cp\u003eAquascape UltraKlear UV Clarifier clears green water algae blooms with advanced UV bulb technology.\u003c\/p\u003e","brand":"Aquascape","offers":[{"title":"Default Title","offer_id":45393082155068,"sku":null,"price":295.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0696\/8675\/5388\/files\/1acec933-53a3-4d94-8514-4977b48402ba_1__75466.1688496688.png?v=1778592730"},{"product_id":"pondmaster-submersible-and-inline-uv-clarifier","title":"Pondmaster Submersible \u0026 Inline UV Clarifier","description":"\u003cp\u003eSubmersible and inline UV clarifier designed to help control green water and improve pond clarity.
