Thank you. I just realized one way to do what you said. I now have a bent up coat hanger hooked to the top of my above ground pool, with an old sock containing CYA in the flow from the single return. Looks like Rube Goldberg, but a milky flow is coming from the sock, so I'm guessing the CYA is dissolving in the current.
