well what did i seen a post on the web.one mod was to make the venturi hole bigger to skim better,and take out the small tube to make it a 2 pass instead of a 3 pass,less harder on the pump.so i got out my drill bit and made the hole 2 sizes bigger and man what a difference,like night and day this thing is skimming mad.its pulling out some nice chunks of gunk.never would have though that stuffs was in my tank.i knew there had to be way to make these things work now lets see how long it skims for,i heard they are real touchy one day work next day nothing.well i got the skimmer for free so no hurt in trying.
