We run one on a well stocked 120 display at the LFS here, not pulling what it could. Not bad at all, but I think it could do more.

So hard to really tell though, so many variables. I do have one available to borrow, I could try it.

I had considered them very briefly, as I couldn't find a local supplier. Deltec have been around since I started reefing and would look at them.

They can be sensitive to changes. My foam collapses sometimes when I'm doing something in the tank. I'm assuming from the oils from my skin. Goes back to normal shortly though. It did start to overflow once recently but I pulled the volute/venturi off the pump, gave it a vinegar soak and a scrub with an old toothbrush and it went back to normal again.

Where do you get your's from?

Not to turn this into a vertex omega 150 thread......but I purchased this skimmer and I am just waiting on my build to finish before actually trying it. What I am wondering is if most people are also adjusting the volute as well as the wedge pipe or if most are just using the wedge pipe and not adjusting the volute and is that why they seem to have issues?

That's also a question I have. Nobody I've talked to has brought this up. Might be the reason for the less than stellar reviews.

Maybe because it is such a new concept that people are not wanting to mess with it to much and just run it full open or closed or whatever and just adjust the stand pipe.

It's possible. Maybe I'll run one for a week and see what I think. Not opposed to going up to the 180i though.

Just watched a review on tht Deltec, guy broke it in 2 places before really using it. Again, German parts = big line of credit at bank :)

Also, what kind of volume you running now? Seems over powered for my tank. 2 pumps??
