Water Flow at Night


New member
Does anyone reduce their water flow in their aquarium during the evening ? I've heard various sources say to connect one or more of your pumps to turn off when the actinics turn off in the evening?

Best Regards,

i would not reduce flow at night.. The ocean's currents arent reduced at night or anytime. I would leave it be. doing that would throw your tank off.

I have always reduced my flow at night. Never had any problems and the room is that much quieter. Actually after living on the coast for some time, the ocean is quieter at night as well, probably due to the wind that is driven by the heat of the sun
