I dont know why am I giving this UV filter 4 stars, probably because it feels a bit cheap, but I feel I am being a bit unfair. This things works great and does exactly what it says in the box.

So apart from feeling cheap everything works better than fine. Oh, one thing, the packaging is not as "tight" as with other items I have bought here. Nothing you can probably do about it thought but bear in mind.

very happy with the product, i have been using it for two weeks now with my reef tank and can see much less alge growth.
the price is less then half what i would of paid where i live.

Great product,works fantastic,great service!

Bought to clear the water and kill single celled algae. Water cleared within a few hours and the green is going. Fast deliver and great customer service.
