Welcome to our forum.
It's not like you're choosing between meatloaf and steak. You'll be happy with either choice. Go with what feels right for you.
Hey, waitaminute.....I REALLY like meatloaf.....
An added benefit Marquis Filtration has is that while filtering they are flowing 60 to 80 gallons every minute through the filters and the safety suction fittings at the floor. The flow throught the suction fittings at the floor goes through the filters with no bypass before the pump. With 60-80 gpm instead of the 4-8 gpm Marquis flowed when they had the 24 hr circ. pump they are able to skim the surface and remove debris from the footwell area, not just clean the middle of the spa over and over again (where does a spa actually get "dirty" ?- surface and floor). Also, now there are no problems with low gpm killing the heaters and circ pumps like the spas Marquis made 9 or 10 years ago with 24hr circ. pumps. With 20+ years now servicing spas I know how important that is. Homeowner's water maintenance gets blamed for these failures so warranties don't have to cover them.

Kudos to Marquis for taking the circ pumps out of their spas. We all know the only true application a circ pump has, and it ain't in no spa!
