How to use Submersible UV light?

- Where should I install it?

It is best to install this light in the filter system of the fish tank or pond. It can't be put directly into the fish living area, otherwise the rays will kill the fish.

It is recommended to use it in these places:

in filter box/tank.

At the inlet of fish tank/pond

The separate space in the aquarium/pond is separated from the fish life area by an opaque baffle.

- Can I put it in the filter in other location??

Yes, just make sure that the fish is not directly exposed to its light, and have the continuous flow of water passes through it, then the water will purified by it.
