Was just lurking around and wanted to add that the circupool cell looks identical to my compupool cell. So it is very obvious that compupool is the manufacturer. I am going on year 3 with my system with original cell. I'm going to do a cleaning on it this year since I have not done it yet but there is almost no trace of buildup on my cell. One thing I did from the start is that I made a little cover to put over my cell to keep it out of almost full day sun just to take that extra step.
