Welcome to our forum.
hi,Right now we are filtering every 12hrs for 4hr duration. can anyone tell lme of their experiences with this subject.thanks john
Another variable is whether or not the filtration system is "100%" or "bypass". My spa is the former and I filter for 2 hours twice daily. I use Eco One, dichlor, a little Sea Klear 4 in1 once a week and NO MPS. Water is perfect with a change every 4 months.
No bypass filtering means that all of the water taken in by all pumps goes thru the filters. My Optima has 3 pumps, counting the circ pump. The circ pump and one main pump pulls water thru the filters. The third pump pulls water thru some inlets covered by nylon "socks", but not thru the filters. That'd be bypass.
