My final update on this matter:

The new venturi is doing wonders, and this skimmer is working well. Pulling very dark and stinky skimmate. Water level is 100% stable. All I can say is wow, it is working well now.

Thanks to Jeremy @ coralvue, he kept dealing with me, even when I may of not been the ideal customer. Thanks, and I recommend his service and products!

Can't wait to see what this baby will do once it breaks in, develops the slime/bacteria buildup within it. Yippeee for me!
