the bermuda's a good skimmer but the pump is in the tank and it requires not a small one either. the CNC is not worth talking about because you wont be able to get one. it pulls more air than the Deltec 600 (it uses the SICCE pump like the octo 800s) and has a real collection cup for $400 but they only make them to order when/if at all.
Why not get another Warner Marine?
If nothing else about the Prizm pro explain the 300g rating? their flagship $350 C skim with Recirc pinwheel and advertised 450lph of air draw is rated at 300g fish only, 200g softies and 100g SPS. their second tier $230 berlin X2 with newly upgraded pinwheel (upgraded from the 18 blade "turbo" wheel the Prizm Pro still uses) that offers 50% more performance than the old pump wheel version and pulls 300lph of air is rated at 225g fish only, 125g soft corals and 75g hard corals yet their entry level old tech Prizm "Pro Deluxe" with the old school redsea "turbo" wheel pump is rated at 300 gallons. so it cant be its pump and it cant be due to size because its 20"x13"x3.5" which is no bigger than the Octopus BH2000 23"x10"x4" which has a much better performing pump and is itself overated at 120g. the warner marine H2 is 18"x10"x4.75" and has a FAR superior pump and is rated at 80g. the deltec is 20"x10"x7" with a FAR FAR superior aquabee pump and is rated at 155g normal/100g heavy stock. so either this "Prizm" design is a miracle worker or their full of BS. there isn't a hang on skimmer on the planet designed to handle more than about 135g and those are the best of the best (CNC, Bermuda, Deltec, Octo 800s). this skimmer is just what it looks like it is a bigger version of a skimmer thats not a great performer to begin with. My local petworld had them on their diplays for a long time and they usually had good nasty skimate production so I know they actually work (they were on two 125g, one highly stocked FO and one neglected high density reef thats been up forever) BUT they dont have the hardware to be anything but mediocre and it sure wasn't doing anything special for the reef tank (not that anything else would have).
get another warner marine or if you want something different or cheaper get the octopus BH2000, its cheaper ($150) and if you want to burn the extra money, for $39 there's a new pinwheel for the OTP 2000 pump you can try out for us.....I mean you.
