Thanks! While we're talking about high tech fittings, does anyone have experience with the koolance quick disconnect fittings. I saw them and thought they might be a good idea for someone like me who doesn't want to constantly be rebuilding his wc loops. I'll *always* be using atx so the length of my tubes should always be the same so for quick block changes these seemed like a good idea. Does anyone have any experience or words of wisdom as far as Koolance and their quick disconnects?
