The aquascape ultraclear UV clarifier effectively clears unsightly green water algae blooms. Its technologically advanced t5 high-output UV bulb maximizes the clarifier's performance, while the narrow contact chamber increases its effectiveness significantly. The ultraclear internal swirl sleeve optimizes uv clarification by increasing the contact time between the algae and UV bulb, increasing UV efficiency up to 50% over traditional UV clarifiers. An on/off indicator provides quick verification of bulb functionality, and the electronic ballast ensures optimum wattage and bulb output. The mechanical safety switch automatically turns the bulb off when the ballast is removed. The ultraclear UV clarifier can be mounted vertically or horizontally using the included mounting brackets, and the easy-to-remove bulb and quartz sleeve make maintenance simple. The ultraclear UV clarifier also carries a 3-year limited warranty. The aquascape UV clarifier comes in 3 wattage output sizes to meet the needs of varying pond sizes, conditions, and water volumes.
