Evan has been showing me some threads here on RC where they ordered a plastic wheel that is made for a rotating scrubbing brush that has a bunch of pins sticking off one end. Another image I saw looked like a small scrubbing pad like I'd use under a buffer (in larger diameter of course) that might work. Finally, in Scott's thread they made a wheel using the leader material of a weed eater. Any of those might help in your quest to perfect your skimmer.
Tanks with taller rockwork seem to look bigger. My rockwork isn't that high but I think my next tank will be 36" high with rock pillars all the way to the top. I'm so blown away with Ralph's tank that is going to be TOTM in September. I think it's my new favourite tank - surpassing even oregonreef.
