Great thread, lots of info read the whole thing, another skimmer recommendation question for you mojo. I have a 55g with 130lbs LR, 20g S/F, it is SPS dominated with little softies and large anemones. Bioload would consist of 6 fish total of abo 18" total, I feed throughout the day keeping them well fed. I'm looking for a long overdue upgrade from my SeaClone. The only space I have is a 5" 7/8 - 8" chamber. I was looking at the Sump Buddy 40, is this overkill for my setup. My budget is <$400 not including if a skimmer needs a feed pump. I'm considering any External skimmers like the Octopus Recirc models, any help to the right direction would be appreciated. I'm also in the process of either upgrading my system to a 120g - 150g, the current 55g display will be turned into the sump over time but will be using my 20g S/F for the meantime till that happens, then it will be a full time fuge. I don't know when im going to upgrade prob the end of the year or next year. Should I wait and pocket my $$ till I upgrade and get a skimmer for that system? I was looking at Vertex in 280 will fit in the 55, but what do you think about Sump Buddy 60? Would another skimmer be more efficient or would the vertex be the best bang for my buck.. What are your thoughts. If it helps, the Upgrade will be SPS dominated.
