Eshopps skimmer review

[blacknife]

I ended up with this skimmer back when leducreef parted out with everything, its treated me ok, not great till lately, not working all the time, this was after a short bout< 2 months or so> of having it dialed in better than ever. I thought it just needed a cleaning so i cleaned it tonight and its still not pulling good. put the pump in water without the air intake on and it goes good, put the air intake on and it starts making noise and cavitating. i got it going as good as i could an hour or 2 ago but its only putting in enough air to make one or 2 inches of air above the water break instead of a nice big foam head like it used to have. Not sure whats wrong with it.

any advice?
I do need a skimmer upgrade soon but I am on a budget so i keep putting it off.

Ken do you still carry this line? ie replacement impellers/meshwheels?
