What is typical for water flow? I have a two speed pump and am trying to figure out ideal run times on high and on low? I'm looking at buying this flow meter (http://www.intheswim.com/Commercial-Pro ... ow-Meters/) but the meter only goes up to 140 gpm. Is that low for a maximum? Is there a better affordable flow meter that you would recommend?
After I know the flow rate are there guidelines for how much time the pump should be on High vs. on Low speed. My Ozone system does not run when the pump is on low. And the Polaris needs the pump to be on high plus the booster pump in order to run.
Also: What is the ideal PH for the pool? The pool school says 7.5 - 7.8, but the pool calculator defaults to 7.2 as the goal when TFP is selected on the bottom of the page?
