I set up a Tunze 9002 Nano skimmer in my 10gal aquarium(1 clownfish, 1 lawnmower blenny, 1 green serpent star, 1 turbo snail,4 dwarf blue leg hermits) 5 days ago and Im still not getting any skimate....do I not have a big enough bio load? does it still need more time to break in? do i need to run it in vinegar water? What should I do??
