Sounds like a cover for the spa is in order. Unfortunately, you can't have a turkey shoot there, or here, either. I tried the plastic snakes for a couple of seasons (not turkeys, other birds) because there's usually a few weeks where seem to be aiming for the pool every spring. Didn't help much. Either the birds are too smart to too stupid to see the snakes as real. Hence the tedious process of washing the cover, which is better than bird fecal matter in the water.
