Skimmer for a 400gal system

[Skimmin]

Thanks for the replys. I haven't quite been able talk myself into spending $1900 for the TC2560 (recirculating Deltec). I've decided I'm going to try the ATI Powercone 250IS. It's rated for 250-500 gallons. If it doesn't do the trick, I'll drop the buck on the Deltec, but figure I'd like to try this skimmer. It seems to have some 'in theory' good features like a meshwheel, digital air meter, and controllable pump. This ones gonna cost $820 so if it does what I need then I can save myself over $1200 on the skimmer and of course... spend it on something else for the tank.lol
