Our Pentair IC40 has quit. No lights at all. This summer is it's 10th season. I'm assuming it is a goner, so we need to replace it asap. What are the latest SWGs that would be great for our 18,000 gallon AGP? I'm looking at CircuPool, which is a brand I'm unfamiliar with, but gets good reviews (Universal 40 or RJ45).
