DIY Skimmer, Rio 2500, Kent Venturi/Beckett

[Les1]

I am in the process of building a DIY skimmer out of pvc and acrylic, as for a pump I bought a Rio 2500, I know they have a bad reputation but at 18 years old I don't have a whole lot of money to spend. The Rio 2500 had a Venturi attachment come with it, but when I hooked it all up and got it rumming it sprayed water out of the air input tube. Have I put it together wrong, or is it really just a piece of junk?
I was thinking also along the lines of getting a Kent Venturi Valve or a Beckett Venturi. I am not to clear on how these work exactally, as far as, I am thinking that from the looks of the Kent Valve it might spray water out instead of sucking air in, just like my current set up. Another Question is I how you need a powerful pump to run the Beckett Venturi, would a Rio 2500 be powerful enough at 748 gph?

I will hopefully get pictures up of this as soon as I get it running.

I am open to suggestions, thanks for your help in advance.

That's not a venturi you can use that they come with, it's more of a bubbler, nothing you could use for a skimmer.

A rio is really not going to power a becket properly, or the kent venturi, you want a good presure pump for either.

Instead of using the "venturi" that comes with the rio..
Take that fitting off the pump. Put the undergravel filter attachment on hte intake of the rio and drill a small hole in the side of it near the pump. Insert a peice of airline hose. You want the hose to be perpindicular to the intake stream of the rio.
Turn the pump on and it should start shooting a bunch of micro bubbles that work well for a skimmer
This is simply based on the needle wheel design of otehr skimmers, minus the needle wheel impeller.
