One added benefit of using the Solapure is that it will keep your pool clean and clear all year round (as long as you maintain a minimal pump schedule).
You can totally eliminate those dreaded first days of summer taken up with pouring in excessive chemicals and scrubbing the algae out of your pool to try to get it ready.
The Solapure can be tethered in a corner, or leave the device to float free, and it will continue to keep the green gunge away so your will need minimal preparation for next season.
You can use the Solapure in conjunction with a pool cover, however you will need to fold one corner back, or cut a small hole in your cover to allow the electrode to be immersed in the water.
