Hello. I have a 75g lightly stocked. Around the holidays I would like to upgrade skimmers. Been looking for something that is built well and won't break the bank. I have heard good things about your skimmers and am looking at the PSK-100 or the 150 Cone. Question, would the 150 be overkill? With my 75 lightly stocked would I see similar performance with the PSK-75? Thanks!
