I agree with Jeremy, this is a no win argument. If there was some magical meter that you could put on a skimmer input and output and measure it's effectiveness, and somehow at the same time control all the water paramaters going in, then you could point to good/better/best skimmers.
But you can't!
So for someone to say that because their skimmer "PULLED A TON OF CRAP" out of their system, so it "MUST BE THE BEST SKIMMER EVER", then all they're really saying is that their skimmer pulled out a ton of crap from their system. No one is to say that any other skimmer would have done differently. Even if you put a different skimmer on that same system right away and it pulled out more or less, you don't really know how the input water quality differed from the skimmer that you just took off the system.
I am disappointed that Jeremy mentioned that Turboflotors weren't even in the same class, as they have been updated with different impellers and pumps, as have many other skimmers, and he failed to mention that.
As far as mine being big and expensive, yep, it was both, but I plan on setting up an equipment room where it will handle an ever expanding system. I don't care about the size, and I'm not interested in an under-cabinet model. So - my TF5000 is right for me, and I'm happy with it. It may not be what somebody else is looking for in a skimmer.
The only skimmers that I don't like are the ones that look like anybody could have made them, if they had access to an acrylic warehouse. Straight chambers, nylon screws, bolt on a water pump and a couple of hoses and PRESTO, you have a PROTEIN SKIMMER! It makes me think that NO engineering was put into the unit, and if priced right, and it pulls out ANYTHING, then it MUST be a GREAT skimmer!
Sorry, but it takes more than cheap pricing and a few passionate endorsements to sell me on anything.
In this reefkeeping hobby, I want to see evidence of a company's commitment to actually RESEARCHING all aspects of the hobby and producing a large range of quality products.
I've never regretted buying quality.......and I've got a LOT of CRAP sitting in my garage that I bought on PRICE FIRST!
