hot tub filter process

[jrb32281]

I have a new hot tub and am wondering how the filter process works. I programmed it to filter every 8 hrs., my question is how long does  the filter process usually last (i have a 300 gallon tub). I"m asking bc it seems like  the jets are coming on pretty often and the tub temperature is at the temperature i have it set at.  I just don't know if it's normal for it to be running as long as it seems to be. Thanks for any help that you can give, Jon.

What brand tub do you have?

Term has a wonderful flow chart that shows exactly how the filtering process works
