I just went from a single speed Hayward SuperPump to a Variable Speed Pentair SuperFlo pool pump. I have a Polaris PB-40 booster pump running my Letro Legend. Both the pool pump and booster pump are on mechanical timers (one for each). I plan to run the VS pump on low at all times. My question is, will my booster pump be enough to really do a good job with the VS pump running on low? Do I need to increase the time my cleaner runs to get the same effect or does the pool pump not really have that much effect on the cleaner? Thanks.
