    Pool looks like its being rocked by a constant earthquake...

    Yesterday I had my Intelliflo VF installed. The installer hadn't programmed one before, so I gave it a go after he left. IIRC I set the pool size at 31k gallons and the run time at 22 hours. This equates to approx. 25gpm and 150 watts (eureka!). I did set function 3 to run for 30 minutes at 50 gpm during one of the off hours (late in the evening) to try to get it to do a skim, though seems like even at 25gpm it's skimming ok.

    So the thing is my pool now has little ripples/waves. Not so much like a rock being thrown in, but rather more like a gentle rocking that would almost be caused by an earthquake. On top of that I noticed small bubbles in the skimmer.

    I know this can't be good (or at least ideal), and I was hoping one of you pros could give me a guess on what the diagnosis might be.

    Adding a random photo of the pool so you have an idea of what I'm dealing with. Built in approx. 1978, one drain, a handful of jets (not sure how many), and something like spinners that don't work for cleaning.



    Thanks,

    Derek

    I can't help on the intelliflo - I just wanted to say your pool looks amazing for 30 years old.

    Seems like something is probably resonating at that speed. Try kicking it up to 21 or 20 hours and see if you notice the same effect.

    Looks like that worked - about 27gpm and still only pulling 175 watts! Thanks for the tip.
