Hi all,
I want to know if its OK to leave the power on in my tanks, when I clean algae off the sides of my tanks. I ask - because - you can see the algae so much better - when the lights are on in the tanks. I use the basic algae scrubber (looks like a green sponge) - in other words - I'm not holding on to (or touching) - anything that is metal when my hand is in the tank.. Thanks in advance.
