So the other day as I doing regular maintenance on the pool, I had a brilliant idea for measuring turnover in my pool. :P Noticing that my spa is essentially 2 differently sized cylinders, therefore easy to estimate volume, I thought all I have to do is isolate the spa and measure the time it takes to empty using a stopwatch.
Would this be in any way accurate? I come up with an estimation of about 5.5 hours for one turnover.
Considering I normally draw from the skimmer only, how much would the added distance to the spa( approximately 17ft ) affect turnover rate?
