Didn't make a difference on sound....We(me and Coralvue) even tried it in a rubbermaid. I tried the stock p/w, the meshwheels, and the large purple pinwheels. The sent me new magnet assemblies and shafts that helped a little. The purple pinwheels helped enough so that I could sell it. David @ Coralvue even admitted that the sicce pumps were loud and the only reason they were using them was to get the price down. That's why they no longer use them and have the new skimmers with the bubble blaster pumps and the askolls. I just hope you have a better experience than I did. If you do your research on RC you will see alot of people complaining about noise issues and you can find alot of the extreme skimmers for sale in the BST forums there as well.
