20 x 40 in ground vinyl in Cleveland. Had been running Blue Torrent AC IMP1500 (constant speed) for 24/7, DE filter with fiber clear. I use a Dolphin Supreme M4 on a regular basis which keeps the bottom clean. This setup has kept my pool crystal clear and once it's balanced after opening, I only have to backwash and replace fiber clear 2-3 times a season.

The pump housing is now cracked and leaking after only 2 years in service. Would I be better with a 2 speed or variable speed and a different run time?

Let me start by saying that I'm mostly a lurker and by no means an expert.

For run time, check out Determine Pump Run Time - Trouble Free Pool.

A few years ago, I switched from a single-speed 1HP to a 2-speed 1HP max. I run on low speed most of the time (except for manual vacuuming), and have a timer for running 3 hours a day (9PM-12PM).

Since I don't have a SWG or any special features, the additional cost of a variable speed didn't make sense for me. However, if I had an inground pool, our local electric company (ComEd) has a $275 rebate for variable speed pumps - the inground restriction doesn;t make sense to me, but it's their program to do with as they want.
