Chronic ear issues from swimming

Anyone ever had issues with chronic ear infections or swimmers ear? I have had them all my life, as an infant to a crazy older lady... They used to occur 3-4 times a year, then I got custom ear molds about made about 8 years ago for swim and showers, and down to maybe 1 every 12-18 months. Last week I started feeling the usual fluid in my ear and tenderness, so I’ve been keeping my head out of the pool water and still wearing my earplugs. Today, it’s officially a full blown ear infection and the ENT used the little vacuum tube to drain it. You all are so resourceful and I was hoping maybe you all had some suggestions that I could take to an ENT dr or fix on my own.
