I also did this mod on the weekend. I used 3 layers of enkamat and zap strapped it onto the impeller sans needles. I had some troubles restarting the pump after that and had to trim some of the enkamat down on the sides and top. Eventually it cranked up and I got even more bubbles than the previous mod I had done (which consisted of me putting a different type of enkamat on over the needles). Foam was nice and milky white but even with the gate valve fully open the foam was too high into the riser tube for my liking. I chopped about an inch and a half off of the gate valve pipe to lower it and the level in the riser was perfect. The skimmer was performing well when I left it but I'm not sure how much more skimmate it has made compared to before.
