The necessary thing in my aquarian economy

very easy to install

seems to be solid, can hide easily behind the aquarium.

Our fish tank was green and ugly, but after using this product the water became crystal clear. Recommended!!

No wite dots whats so ever on my Paracanthurus hepatus!

Really good for very good price!

excellent product

Excellent produit !

I use it after my Resun CY20 filter and it works great for my marine tank!

With this Sterilizer during two weeks Iâ??m fully exterminated Ichthyophthirius multifiliis without any little drop of chemic cure into aquarium! This method is absolutely safe for fish and plants.
Thanks to fish-street --
Best device for best price! :-)

Good build quality, got one year out of the bulb. But replacement bulbs are so cheap i didnt care. keeps the algae under control. You wont regret buying this.
