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.

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.
