Hey SM-

Buddy of mine got his surf scrubber from you about two weeks ago. I wasnt there when he set it up, but it sounded pretty simply.

Its about ten days, and there is no growth to speak of. However, he does not have it on a timer, and its running 24 hours a day.

I believe i know the answer, but would algae not grow at ALL if lights were left on all the time? He wanted me to ask you, so here I am.I told him in needs to be on 18 hours a day, but he tried telling me something should still have grown in there.
