The SRO line are beasts for sure. The bubble blaster is great at pulling lots of air. I had a 3000. It did pull a lot of skimmate. I didn't find it very consistent though which to me it would periodically turn into a volcano. Those neck extensions are a big plus and highly recommend at least one for these skimmers to reduce that chance.
I also went through 3 pumps over the years I ran it which CoralVue is great for support. Those pumps are not cheap for a Chinese made pump.
I eventually tried out a cheap seaside aquatics with a sicce pump. Not a very strong skimmer but was amazingly consistent.
One of my favorite needle wheel skimmers though, if you can find one, was the Aquamaxx EM300. Great bang for the buck. Also a modified sicce based pump. Not as powerful as the SRO 3000 but nearly as much production but even more importantly extremely consistent in its production. Plus a lot cheaper.
But if you have the height I just can't believe how much production and with the consistency my MTC MVX skimmer produces (6-8 cups dry skimmate per day). Hands down best skimmer I've used. May not be the best skimmer ever but I don't think we'll ever know what that is. It was probably some downdraft recirculating airstone driven skimmer. Becketts are damn nice too but more maintenance on the injector.

This thread sucks with out pictures.
My favorite. I call it upside down dairy queen blizzard thick.
Can see how sticky thick it is. Survived and stayed together through unscrewing and taking it off the skimmer in my basement sump, walking up some stairs, dodging dogs, cats, kids, toys, etc, brought outside, placed upside-down on porch table, quickly take a picture before I have to dodge wife complaining that nasty thing is on the table, brought out to the yard and lid unscrewed off. Foam still intact. lol
