What would be better skimmer to get? I have the option to buy a brand new PS-3000 Pacific Coast rated for 400 Gallons or would you pick a used ASM G-3? I believe the G-3 is rated for ~250Gallon
Also check the Super Reef Octopuss line of skimmers. I have the SRO 5000 external. 90 SCFH, no DIY, pump always starts, virtually silent and it has fail safe design that shuts down skimmer production if it fills your waste bucket.
