Well it is rated for a bigger tank.

But ya, it is definately a tad more efficient. The RS-100 is my favourite model.

I wouldn't say the larger pump would be more efficient, in my experience smaller pumps have higher air to water ratios. I believe this is partially why larger skimmers tend to use multiple smaller pumps rather than one bigger pump. Of course the the larger pump will bring in more air but uses more power, so you can't make any claims about efficiency without at least knowing the air flow and power consumption of the pump.

Personally I would probably go with the 80, it's smaller which would probably be better considering space may be a concern with a 33 gallon aquarium and because I've seen a few 100s and 135s have problems containing air bubbles, again a big concern if a small sump is being used. Going bigger isn't always better, the larger pump on the 100 will likely cause more turbulence in the small body and since euro-reefs don't have diffuser plates it may not be as effective at skimming less stable proteins.

thanks can't explain how much that helped!
i actually found an rc-80 for a decent deal, what do you think about these as opposed to RS's? i noticed as you mentioned the use of multiple smaller pumps, such as on the RC's..

Never actually seen an RC80 but the RC models are definitely better than the RS, they have better craftsmanship and use the better Ehiem pumps. They can be used external, is that your plan?

Same thinking here...
I don’t know why so people tend to overlook air intake, imo this is the most important detail in the skimmer’s performance, second would be quietness and power consumption.
For a sub $800 I would buy a skimmer with at least 600L/hr air intake, quiet and easy to clean, if the unit is more then a $1000 it must produce at least 1200 L/hr of air intake and would consume less then 90W or so of energy.

So disregard fancy names and marketing; check and compare the specifications.

EuroReef has seriously dropped the ball as a company. I'd look elsewhere

the thing i like about them is all the great reviews they're getting, and you seldom hear about typical cheap skimmer problems like how sensitive they are to water level and clogging needle-wheel, etc. then again the next best thing would be the smallest BK, overkill for my tank no doubt, so anyone gonna chime in for the RC's?
