I'm so convinced of this mod, I think *any* needlewheel based skimmer would benefit from the mod.
I even think that this could breathe new life into older venturi model skimmers with a few extra mods. For example, those skimmers usually had the venturi between the pump and the skimmer (and just had a regular old impeller in the pump). Change it around so that the venturi is on the pump intake instead of the output, mod the impeller, and see what happens. In fact I regret unloading all my old venturi skimmers now because I really want to see what kind of difference it could make.
In fact, I'm now so convinced of this mod, that I'm considering unloading my two beckett skimmers. And I *love* my PM Bullet-1 skimmer, it has been an absolute workhorse for the last 5 years for me, it's been an incredible skimmer so to say I'm ready to consider selling it and going to all meshwheels should say how much I believe in this mod now.
I feel silly for waiting so long to try it.
