I am in need of one protein skimmer under $450 that can stand alone insump so i can take it to one sump on one day and then take it to another sump on a different day. I am setting up (5)30 gallon broodstock tanks with a sump that will fill to about 12 inches in depth, and i have 3(65) gallon tanks for growout with its own same sump the same size.. i am trying my hand at breeding marine fish.... i want to be able to skim one sump for a few days, and then take it out to skim the other sump for a few day, etc. what type of protein skimmer so you recommend? i currently own a tunze 9010 in my 90 tank. Thanks. Bunker
