I would think the above would work for 600 gallons, if not Orca can make you whatever you want.

another option would be nice becket, like the above, requires a big pump, but boy do these work! The 830 or 848 would work well.
Yea, but then the pump breaks and no one around to help!!!<a href=showthread.php?s=&postid=10136720#post10136720 target=_blank>Originally posted</a> by DeltecRules
I would go with this one if you are going to skim the hell out of your SPS tank

Meaningless "ratings" aside, I would put the $1668 ER RS500 as similar in performance as the $2200 H&S A300 and the $3150 Deltec AP703. The 3 have nearly identical specs. It is the standout value in this size skimmer. The ER RC750 and Deltec AP1003 would be a step up in performance above the other 3.<a href=showthread.php?s=&postid=10139434#post10139434 target=_blank>Originally posted</a> by Reef Sponger
ER and H&S replacement Eheim pumps are approximately $300/ea. Deltec replacement Eheim pumps are $550/ea., almost double.
Didn't catch the 600g SPS, then you've got to step up to:
H&S A300-3x1260 $2200 1000g capacity
Deltec AP1003 $3270 930g capacity
Euro-Reef RC750 $1998 750g capacity
I would highly recommend the H&S A300, best quality built out of the 3 skimmers and performance should be similar on all 3 units. If you have some height contraints, Then go for the:
H&S 300-3x1260 $1900 1000g capacity
Deltec AP703 $3159 530g capacity

The concern I have with using "common sense" and gauging things like body shape and size, air capacity, and etc. is that it seems like none of these factors' effects on skimmate have been quantified...
Is it true that we don't know how tall vs. fatter correlates to skimmate production?
My point is when comparing swimmers with nearly identical specs and design, but with wildly different "ratings", use common sense. I was not posting about skimmers with different designs.Common sense for one. Look at the specs of the skimmer. Body size, technology, air draw. When you have three skimmers with nearly identical specs, there may be some small differences in performance, but not 2x the skimming capacity from one to the other.

In terms of needlewheel type skimmers, the biggest hype is on the new ATi Bubblemaster skimmers. They do really perform well. There is 3 really long threads on information on these guys and here's the link to the 3rd thread:

I would suggest that Tunzes and BMs be discussed on another thread so that we don't continue to hijack this thread. The thread starter is looking for a good skimmer for 600g system and both these skimmer lines don't qualify.

I don't think 10" in diameter is nearly enough for a 600g tank. I'd say a 18" diameter is a must for a 600g tank.
