Hi, first time post. What should my pump settings be? I have an ecostar that can be set to 4 different speeds. The electricity rate for peak (currently 12PM to 7 PM) is 4 time the rate for off-peak. What should my settings be to effectively clean the water and minimize my utility bill? And, if it helps, the piping is mostly 2 inches, there is a shear waterfall, an in-line chlroinator, aerator, and heater. TIA
