Been there and done that with the springtails. We came home from a three day vacation to find the entire surface of the pool COVERED in them. We are still kind of fighting them, but just a little here and there. Our pool is new this year, and we laid sod all around it. We think that's where they came from. Dawn definitely kills them, but I was worried about putting Dawn in the pool. Instead I bought a plastic tub that I fill with a little pool water and squirt two or three drops of Dawn in it. I slosh it around a little, and use a handheld fine mesh net to scoop those suckers up and dump them into the soapy water. They drown almost immediately, and the soap stops them from being able to jump out of the water. We initially had to do it every day, but in the last month we've had just small amounts of springtails to scoop and mostly then only when it rains. It takes less than five minutes to scoop them. I think we are winning. At first, though, it was horrible. We used our big net to scoop them but had to use clothespins to pin a piece of tight knit fabric in the net because the springtails are so small they fit through through the holes of the net. So I cut several pieces of fabric for the job. We clipped them into the big net and scooped lots of springtails and dropped the bug-filled fabric into the bucket of soapy water. Repeat with a new piece of fabric. When we had most of the bugs out (for the day), we'd let them soak for a bit in the soap to be sure they were all dead, then hand-washed the fabric at the hose (away from the pool) with Dawn so it would be ready for battle the next day. It took about a week of dedicated work, but we didn't have to put chemicals near our pool on our fresh sod or soap in the pool. That effort knocked them down to a much more manageable load. We NEVER ignore them. When we see them we scoop them and kill them. I'm praying the coming winter kills them so next year they aren't an issue for me and you both!
