Clear Your Pond Water with the Aqua Ultraviolet SL 200 Watt Plastic UV Unit
The Aqua Ultraviolet SL 200 Watt Plastic Body UV Unit (Item # AS90201) is an industrial-strength water treatment system engineered specifically for larger ponds, expansive water features, and commercial aquariums. This model features a lightweight, rugged plastic housing that simplifies installation and maintenance while delivering heavy-duty water clarification and sterilization performance.
Sterilizer versus Clarifier Performance
When utilized as a complete water sterilizer, this ultraviolet unit effectively eradicates green water, controls floating bacteria, and manages water-borne pathogens to protect the health of your fish. When used strictly as a water clarifier, it reduces single-celled algae blooms to keep high-volume systems beautifully clear.
- As a Sterilizer: Handles up to 9,200 GPH for freshwater pond sizes from 17,000 to 22,000 gallons at a 30,000 microwatt per square centimeter end-of-lamp kill rate. For marine saltwater setups, it treats up to 1,800 gallons at a 90,000 microwatt per square centimeter kill rate.
- As a Clarifier: Controls green water in a freshwater environment up to 30,000 gallons at up to 15,000 GPH, assuming the pond has 50% to 75% plant coverage or partial shade.

Frequently Asked Questions
Q. What is a sterilizer?
A. A sterilizer will eliminate green water, control bacteria, water-borne pathogens, and safely control fish disease.
Q. What is a clarifier?
A. As a clarifier, the single-celled algae in your pond will be reduced or eliminated.
Q. What is the difference between a sterilizer and a clarifier?
A. As a sterilizer, your Aqua UV system will keep your pond or aquarium water crystal clear. In addition, you will have the added benefit of bacterial control which helps keep your fish healthy and happy with less risk of disease. As a clarifier, your pond will still have a green tint to it unless you have 50% to 75% plant coverage or your pond is in full shade.
Q. How often should I change my lamp?
A. The lamp should be changed after 14 months of continuous use.
Q. Is this unit submersible?
A. No, this unit should never be submerged in water.
Q. Can this unit be used outdoors?
A. Yes, this unit is designed for both indoor or outdoor use.
Q. Does this UV unit include a pump and tubing?
A. No. Every pond layout is different, so it is difficult to include a one-size-fits-all pump and tubing kit.
Q. Do ultraviolet lights kill string algae or algae on the walls or liner?
A. No. Ultraviolet lights only kill single-celled algae that passes directly through the unit. It cannot control or eliminate string algae attached to your rocks or liner.
Q. What should I expect after my UV is installed?
A. If your Aqua Ultraviolet system is installed after your filtration system and is properly sized, your water should be clear in 3 to 5 days, and sometimes overnight. If installed before the filter, the water should clear within 7 to 10 days. The green algae attached to the sides and bottom of the pond will not disappear, as this is completely normal for a healthy ecosystem.
Q. Is there a difference between a black or white ultraviolet unit?
A. No. The color of the body does not alter the effectiveness or life expectancy of the unit. It is purely a personal aesthetic choice.
