How long do you run your filtration system daily?

I have mine set for 2 hours twice a day which is more than the default, but am wondering if longer is better?

Depends on how much you use the tub. Is 4 hours a day enough to keep your water clean?

While your tub might be set for a total of 4 hours - you have to add whatever time the tub is kicked into heating mode to maintain your temp.  Thus - throughout the day your tub might be jumping into filter mode to catch back up to the desired temperature.
