I installed my RAIN-2 algae scrubber 14 days ago.
Following the instructions, I have 1 of the 4 lights connected for this time.

I'm assuming that I shouldn't try to clean off the growth, but I can turn on a second of the lights - perhaps on the other side of the cover?
Is there anything else I should do?
When do I check for growth again? In another 14 days and then do my first cleaning of the algae?
