I noticed in my lurking that more than a few of you have the CompuPool CPSC SWG's. Have any of you opened up the cell for cleaning? I inherited this SWG with the pool. The previous owner claims it's only 2 years old and he only used it for about the first 2 months, couldn't get it to work right so shut it off and started using chlorine tabs. There is a white buildup on some of the plates which I'm assuming I'll need to get off? before I attempt to use this device but I'm scared I'm going to break the housing. The owners manual isn't real helpful, it just says to turn the cell upside down and pull it apart. This doesn't seem to be working. Any advice would be greatly appreciated.
