Hello to all

I want to change out my old single speed bronze pump with a 2 speed pump for energy savings, I can not afford a variable speed pump at this time. My question is I have read that with a 2 speed pump you need to start the pump in high speed for a minute or two, to prime the pump before switching to low speed operation. If so what would be the best / affordable way to control this without going out every day to flip the toggle switch.
Pool discreption 18000gal inground, 500gal attached spa, spa has seperate pump, 2 speed pump will be used for circulation and cleaning, supply and return are 1.5", has Hayward C-3000-s filter, equipment is about 45' from pool, no rise.
Thanks for any help
Robert
