you are frobably frustrated at the darn thing for not staying adjusted right
(i sure was!)
KEEP the turbo venturi attachment when u pitch it
and when i modded my current skimmer i did the needle wheel mod to my mj 1000
the turbo venturi works GREAT
this skimmer (modded) is just pulling all sorts of junk out
(HAVE to empty the cup out every other day)
my current skimmer is an excalibur hv1 hob
best one so far
this setup works even better than when it was NEW!
hopes this helps at least 1 person.
