Questions on changing to a 2 speed motor on a Hayward Super II pump

[waterbear]

The Hayward filter is very undersized for this pool (and I have a guess as to who the builder might be since I have seen several pools that have been undersized on this filter). I suspect that the filter requires cleaning every week or so. particularly with the seasonal pollen problem here and the oaks. A pressure side cleaner or a robot would do a better job of keeping this pool clean than an in floor system. They ar basically worthless for the type of stuff falling into this pool!

The two speed pump would be an excellent idea and keep it 2 hp since you probably need that for the spa jets but I would also consider upgrading the filter to something larger such a a Pentair clean and clear plus for a pool that size.
