I think a lot depends on how big of a tank you have. If you have a 29g nano then you might not like the remora because the pump for the skimmer is located in the tank.
They are notoriously difficult to adjust. If you can see the control piece move, you have probably moved it too far. The advantage of a prizm on a nano is that very little of it is in the tank. I took my Prizm off of my 75g and put it on a AGA 7g minibow nano and it works awesome for that. When I then put my remora pro on the 75g, I was shocked at how much more skimmate I was getting.
