I did the Meshwheel Mod to my ASM G3 last night. I has made the performance of the skimmer go through the roof. I have a really low bioload as it is, but my skimmer is still pullling out some pretty sick skimmate. I give the mod a thumbs up...I think everyone with a middle of the road needlewheel skimmer should do it if they want to improve their skimmer's performance.
