I am absolutely torn in trying to decide which Stenner pump to get. Either a 3 Gallons per day, Fixed Rate, Single Head, 100psi, or a 10 Gallons per day, Fixed Rate, Single Head, 100psi. Well hey man, no problem. What's your daily chlorine useage? "Wait.., what? I don't know." What do you know? "Well, that in 138 days of pool operation last year with an LQ, I used 164.5 96 oz jugs of 6% bleach." Wow, that sounds like a lot. "Yeah. My FC comfort level is 8-ish." O.k., by my math that equals an average daily useage of 114 ozs a day. So I would recommend the 3 gallon Stenner pump. "It's not that simple, that's an average over a pretty good length of time with extreme temperature/sun conditions. Also I'm upgrading to a 2 speed 1.5 hp pump this year with a 10 event timer." O.k. Do you think you used more than 3 gallons a day at any time during those 138 days? "No." All right then, I will hold my ground and reiterate my 3 gallon pump recommendation. "But, (and here's the question) is there any advantage to running a bigger pump for a shorter period of time as far as wear and tear on the pump itself? Is it a real mechanical advantage or a perceived comfort level?"
