We just bought a new marin hot tub it is up and running everything is find .I have a question concerning the time the filter needs to run.I contacted the Dealer and they are very vague with their answer.The book states that the factory preset is for the filter to run 24/7 in the standard mode.I could switch to the economy mode and it will filter I think every 6 hours for a half hour.It also states that in the standard mode I can change the settings for the start time and the run time.I am totally confused at which way would be the best for filtering.
