The UV-C exposure damages microscopic free-floating algae, allowing your pond filtration to remove the affected material more effectively.\u003c\/p\u003e\n\u003cp\u003eIf your pond has gone from clear to green as the weather warms up, a properly sized UV-C clarifier can be one of the most effective tools for getting the water clear again.\u003c\/p\u003e\n\u003cp\u003eAvailable from Simply Fish in

numbers of microscopic algae suspended throughout the water.\u003c\/p\u003e\n\u003cp\u003eBecause the algae is floating rather than attached to a surface, you can't simply scrub it off.\u003c\/p\u003e\n\u003cp\u003eA UV-C clarifier works by continuously passing pond water past an ultraviolet lamp.\u003c\/p\u003e\n\u003cp\u003eThe treated algae can then clump together and be captured more effectively by your pond filtration.\u003c\/p\u003e\n\u003cp\u003eThis is why a UV-C clarifier works best as part of a complete
