We have been getting soooooooooo much rain lately and more heavy rains expected around 6:00 this evening. I have drained anywhere from 2 to 5 inches of water out almost every night this week just to keep it from overflowing. Not only is it screwing up my water chemistry but it is a major PITA. I have Googled everything I can think of as far as automatic overflow protection with no results. Does such a device exist? Surely I'm not the first with this problem.
