Can't get new skimmer pump to work right

[hrdneglcry]

I have a Euro Reef Skimmer. I was running a Rio 2100 pump on it that I attached a venturi nozzle to. It worked very well. But the Rio failed and I purchased a Jabeo DCT 4000 and was sure all I had to do was attach the venturi nozzle and it would work just fine. I glued the nozzle to a threaded fitting and screwed it in. But the bubbles are not micro. They are large and the skimmer quickly overflows even with the pump on low. I'd glue it right on the pump but if it still doesn't work then its stuck to the pump. Skimmer is a good skimmer. Can't find a venturi nozzle for Jabeo. Any ideas as to what I could try?

Take a pic of the new pump and venturi please.

You need a needle wheel impeller. Jebao does sell a needle wheel pump, don’t know if you can purchase just the impeller or if it will even fit. Contact fish-street and see what they say.

Plenty of other options if you buy another pump with a needle wheel and Venturi.
