This evening I will take a reading at sunset with my kit. Tomorrow will take another one at sunrise. I have a variable speed pump. Should I leave the pump all night running at full power or 50 or 60% of the power will suffice?
The reason I ask is not because I am worry about the power bill. Not at all. Next to the pump there is a bedroom and I don't want to disturb my friend because of the noise.
Look like a silly question but I just want to do the test properly.
Thank you!
