my expierience with skimmers is that these particular pieces of equipment are by far the most controversial {SP} parts of a salt water tank - -after much reading and studying I've found nothing other than personal preferance with these things - -I just bought a used Red Sea Prizm from a friend of mine, set it up and it was making skimate within an hour - -yet on some sites I read that this skimmer was the biggest POS ever made - - so my advise - set up your JEBO and if it works ....Great !!! if it don't your only out 60 bucks and you can resell it to someone who might like it on EBAY - I'm upgradeing to a 65 gallon tank soon and will be buying an ASM G2 skimmer or the sump - -pretty pricee but a lot of good reviews - - good luck
