This is a very helpful forum. I have been on for two days now and have learned a lot. I am an electrical engineer for an aluminum cable manufacturer, hence the name cateng. I am a huge kentucky wildcat bb fan so that is where the cat part comes from. My new wife and I just purchased a house in January that has a 20,000 gallon inground pool with liner. I know nothing about pools so I will be very reliant on this site. I love being outside and creating things with my hands so I am very excited about making improvements around the pool. Aside from being an engineer I also do woodworking on the side, mainly finish work (cabinets, furniture, trim, etc).
