OXYFUL 36W Non-Submersible UV Ultraviolet 21.5" Clarifier offers top of the line technology that purifies your water through an external filter. The filter technology utilizes UV lights to keep your ecosystem looking clean. You can utilize this device in freshwater aquariums, saltwater aquariums, and outdoor/indoor ponds.
For saltwater aquariums the UV clarifier can remove and prevent a number of problems. UV clarifiers are invertebrate safe, so they will not harm your shrimp, snails, and hermit crabs.
Instructions:

- The Oxyful ultraviolet clarifier can be installed vertically or horizontally. The best place to install your UV clarifier is AFTER the filter.
- If it is necessary to install the clarifier before the filter, adequate pre-filtration should be used to prevent the quartz sleeve from breaking from debris.
- The rubber ring will go in between the inlet/outlet, while screwing the nut on top to tighten the seal.
- On/Off is managed through the plug it is connected to.
