Over the course of last year I also developed a massive aiptasia issue. Almost got out of the hobby due to them because I had no clue what to do or how to deal with them. Then I figured I’d try something radical for fun. I had a jug of 35% hydrogen peroxide laying around that I use to treat algae in my pond. I decided to fill a needled syringe with it and inject the aiptasia with it. This was 100% effective and very satisfying. The aiptasia melt away from the inside out and liquify into water and oxygen. I did a few a day for a week and now they are all gone. If I ever see one again I just whip out the syringe and nuke it right away
