Swell 55w PLL UV replacement Bulbs / Tubes are ideal for UV clarifiers, filter sets and any pond equipment that uses a 55w PLL twin tube, four pin lamp.
Utra Violet light binds together algae cells for easy filtration and removal. Left unchecked algae can cause thick, murky water that starves fish and plants of oxygen, light and nutrients. Our own brand UV lamps ensure that your pond looks great all summer long.
