Aquarium UV Sterilisers

UV Sterilisers for aquariums are clever devices for keeping your aquarium free from unsightly build ups of algae blooms.

Algae is free floating and particles can be too small for your existing filter to pick up on. This means algae can pass through your filter many times before it has developed enough to be picked up by your filter.

By adding a UV clarifier to your aquarium's filrtraion system, you can pick up more algae than normal.

Clarifiers work by allowing the tank water to pass by a fluorescent tube emitting Ultra Violet light which causes the algae particles to 'clump' together so the filter media can handle it.

At Swell UK there's a huge range of UV clarifiers available at discounted prices and made by respected aquatics experts. Order before 3pm weekdays and if your item is in stock we can despatch it from our distribution centre the very same day!
