Well it looks like the Cool-N-Save may be a bust.
It's been a mid to high 90's all week so the AC has been getting a little bit of a workout. We have extremely hard water here and although we have a water softner it is not plumbed to the outside supply. This is the build up after 5 days of fairly hard use. The filter is not able to filter out the deposits. I'll see how hard it is to clean off the stuff this weekend.
