Bought a new AG pool; now need to figure out pump and fitler

[K9SwimCoach]

That's a good idea, to get Ben's input. I gather Louisa's pool will be a commercial enterprise used to swim dogs. That presents an entirely different filtration issue from a pool used by children. She won't have to deal with urine (dogs don't pee while actively exercising) but she will have a lot of dog hair. No sun tan lotions but dander, instead. In my mind, for her 9,000+ gallon pool she'll want a pump and filter that does the job reliably well, not just something that'll get her by.

You're correct in that the pool will be used in my business for dog swimming. I have an indoor swimspa that is used for canine hydrotherapy and the larger AGP will be used for more athletic dogs. My 3000 gallon swimspa has a 3/4 hp 2 spped pump that seems to work well with the 175 pound sand filter for getting the water pretty clear after a full day of furry dogs.

Yes, dogs will get water on everything. Even on places you wouldn't think. When they shake, water really travels great distances. And no one ever leaves the dog spa with dry clothing!

I would love to get by with a 2 speed pump, but another pool retailer told me that it will be hard for me to get a 1 HP pump because they're not energy efficient and being in California, it's a problem. According to him, oversizing pumps has become such an issue that the State of California (a big pool state), recently enacted a law to control how big of a pump could be placed on a swimming pool.

I haven't yet been able to find out if there are energy efficient 2 speed pumps. Does anyone know?
