Can I store the chemicals in the same bin as the robotic cleaner? One pool supply shop said I should keep the chemicals away from a grill or the garage because over time they will corrode metal. I would assume the same would happen for the robot if they're stored in the same bin. I have a Pentair Kreepy Krawly 920. The manual doesn't say anything about storing it with or away from the pool chemicals. I'd just rather not buy another separate bin for the robot itself so we don't have several bins around the pool. Thanks!
