Hello, I'm looking purchase one of these three protein skimmers. I have a 90gal. with medium bio-load. I do tend to over feed a little. 1. Reef octopus 4 2. SWC extreme 160 cone 3. Bubble Magus BM-NAC7 cone. Which one is the easiest to adjust and does one last longer than the other as far as the pump goes. Any suggestions would be very helpful. Thanks.
Are sea hares reef safe? i.e will that eat sps, lps, or polyps?? i know they are awesome for algae but just wondering how reef safe they really are
