[mytank90]

i have the tunze 9005 in my tank<no sump>the unit itself is roughly 15 inches high and you need 7inches above it to get the cup out.i also found bye running my tunze on a timer and letting it turn off for about 1 hour it seems to work better

this might be a dumb question, but does the whole skimmer go in your tank or hang on the back? I can't seem to find any pics of one in a tank. I have a sea clone and it seems to work ok, but it sounds like a '76 mazda 808 (my first car)
