We have an inground pool with probably approximately 24,000 gallons or more. It is 18 x 36-foot rectangle. We purchased the home 4 years ago. We only have experience with above ground pools. The pool company we usually use were unable to open the pool d/t a broken motor. We replaced the motor/pump on our hayward filter. Over the weekend we took the winter cover off and I have never seen so much algae in my life. We have had the electric checked bc it was tripping the breaker. Since last night it has not tripped the breaker. It will run with the garden hose in (it is not pulling any water from the 2 skimmers). With the hose one of our 3 jets was working barely. It kind of works on recirculate and backwash. We have very limited knowledge on the plumbing situation. It is at least 30 -35 years old. Help! I know I am all over the place and vague, but I am trying to get some info while my husband is working on the swamp! Thank you I will post pics.
