Red Sea Berlin Hang-on Protein Skimmer

 

Looks like I hit the jackpot on this one, thanks!

 

You'll want a rio 2500 or 3100 for a pump.

 

Ya I read that, do you know If it comes with a venturi attachment?

 

I used to have that skimmer about 5 years ago, it worked okay. It has a venturi built in, I edited your picture to illustrate

 

Thanks! I already put it in my system once it's tuned in it works fantastic. I bought a pump with venturi also but I covered the whole for it. As of now, my params are zeroed out because of it.
