I have an IC60. I think it's officially 4 years old though I may be off by a year and it is actually the warranty replacement of the one I got at that time. It has been nothing but trouble. Every year I take it out and put in a pass through during the cold months, and usually I'm well into swimming weather before I get it producing well enough that I'd trust it if I went out of town for a week. So here we are again, it was cleaned and put away last year and I've had it hooked up for a month and it says "bad flow". I'm at my wits end with this thing. What are you're recommendations for a 36k gallon pool?
