its not that seclones dont do anything, when i had one running i would fill the collection every week or so with a greenish skimate - the skimmer i have now (rated for a 400gal tank on a 100gal system) empties the collection cup into a 2gal bucket that fills about half way with dark black liquid in a couple weeks (the seaclone collection cup holds probably 4oz-6oz of liquid), and i skim dry! the skimate in the collection cup riser tube is like a solid 1/8 inch thick that needs to be cleaned at least once a week
the fact of the matter is that seclones really arent that cheap (usually $100-130) it would be one thing if they were like 40$ id say they were a decent product for the price, but not for the price thry ask for them - its worth to pay at least 200$ and get a product that will be worth the cost - once you see the production of a higher priced skimmer you'll never skimp on a protien skimmer again
