There is no on-off switch so u would have to unplug it to turn it off. U would have to leave it on constantly until ur problem is fixed probably about 3,4 days but after that just plug it in when ur lights r on. If it is water born algae it is probably because of ur lighting system. My tank was so bad I could hardly see my fish unless they were right up against the glass. I hooked up the ultraviolet light filter and after about 4 days I had crystal clear water,and it has been that way for 8 months now.
