We recently bought a house with a 15,000 gallon pool and spa with a water slide. We've been having issues with it since we got it and are not impressed with the people who owned it previously. The pump they installed is a Whisperflo high performance 2HP pump and the filter has a design flow rate (gpm) of 120-150, which seems really overkill with a 15,000 gallon pool.
The filter housing just cracked up the side so we need to replace it, and I'm wondering what the best course of action would be. Would it be more beneficial to just replace the pump with a smaller system, or should I figure out a filter to go with our pump? I know little to nothing about choosing filters and pumps. I've attached pictures of what we have currently.
Thanks in advance!
