There seem to be 2 distinct schools of thought about separate circ pumps.
What's the general consensus out there? Are 24/7 circulation pumps:
a) More economical to run than cycling the jet pumps for 6 hours /day?
b) Quieter than bigger pumps?
c) More likely to wear out sooner because they are smaller and running 24/7?
I like the idea of having a dedicated pump for circulation but I don't know anything about their longevity. I've also heard stuff about stagnant water/sediment in the jet lines with the smaller circulation pumps. It also makes sense to me that adding another pump would add to the cost of the tub but I haven't really noticed that in the market. Any easy answer out there?

There are 3 shools of thought:
1--No circ pump
2--Small circ pump
3--Large circ pump
They all have their advantages and disadvantages. There will be no easy answer to which one is best.

I'd wouldn't have that issue very high up on my list of spa selection criteria.
It's all just a slightly different way to filter the water. If your water is clean, then your filtering system is effective.
Some food for thought:
My Optima uses the small 24/7 circ. pump coupled with a 2 speed main pump, pulls water thru a different filter, and runs 4 times per day, up to 24/7.
So far I can say:
My circ. pump is almost silent. But the main pump on slow speed is very quiet too, just not quite so much as the circ. pump. But I use both for filtering, not just one.
I've already had one circ pump replaced under warranty, at about the 30 month mark.
Not sure if my small pump running 24/7 will wear out faster than a larger pump being switched on and off four times per day.
So far the large pump is winning that war. It's not needed service yet.

Larger circ pump should be roughly the same cost as reg. pump on low speed for that amount of time (give or taike just a little bit)
b) Quieter than bigger pumps?
Definately quieter
c) More likely to wear out sooner because they are smaller and running 24/7?
Smaller circ pump (9-10 gallons) would be working a lot harder than a larger circ. pump (30+gallons)
Any easy answer out there?
There's a lot of different opinions about circ pumps so there really isn't an "easy" answer. Take in all the info. and try to avoid all the "sales" jargon and hype.

A. That is a myth
B. Depends on the brand
C. Most pumps big or small will last a long time. 95% of the pumps I change are because of the consumer neglect.
Personally I do not like the small circ pumps, the more water you can filter the better off you are. Circ pumps do have their place though, it is called garden pond.

Circ pump or not is not that big of a deal.
I have a large circ pump and it does hum - the quietest pumps are the ones that aren't on! But having a large therapy pump may disturb you and your neighbors if it's running for 3 or so hours at night if your trying to sleep. My pool has a 1 HP pump and you can hear it when it kicks on at 4 AM. It's far enogh away from the house that it's not too bad.
Circ pumps may be the way to go IF you want to run ozone 24/7. This is dependent if you believe ozone works the way it is sold by some dealers.
