The Tunze nano skimmer 9004 is in my 20G reef aquarium.
I never had one full collection cup, I can let it run for a month it will never be full.
I moved it up, down, shortened the air line tubing, doesn’t matter.
Also the skimmate is very wet, this is because there is not enough foam.
An extra downside to this skimmer is that the air input in the motor is only 2mm or so (very small hole) The moisture in the air around the skimmer contains salt and therefore the air intake on the motor will get clogged with saltkreep.
I have not tried the others from the list, but I’m sure it does not deserve a 1st place.
