I just picked up a used IN-80 for my 75g setup. Anything I should know? I have read back through the thread, almost all 1,000 posts.
I have the output pipe raised up to the water surface to reduce back pressure in the body. Skimmer is running in 8'' of water in my sump.
It is starting to pull skimmate already, under 24hrs of use.
Thanks guys!
