The check valve between the spa and the pool is defective.

I wouldn't.
A lawn layer is sod that is put down on plain dirt to create a grassed area, or lawn.
I would NOT do that unless I were certain that the spa was built and designed to handle the change. Salt water can do serious damage to components that were not designed to withstand it.
To apply Epsom salt on your lawn, dilute 2 tablespoons of Epsom salt in a gallon of water and apply it to your lawn using a sprayer or watering can. Make sure to water the lawn before and after application to help the Epsom salt penetrate the soil. It is best to apply Epsom salt in the spring or fall for best results.
Having a spa in your garden may attract bees depending on the plants and flowers you have nearby. Bees are attracted to bright colors and sweet scents, so having a variety of flowers may increase the likelihood of bees visiting your garden. However, the presence of a spa alone is unlikely to significantly attract or deter bees.
give up and hire a lawn service...
