So I have only a tiny pico tank ATM, but Santa's bringing us an IM Nuvo 40 AIO for Christmas.
I've never used a skimmer before, and I'm considering adding a HOB skimmer, but I keep seeing that they require X-amount of clearance. Is this clearance upward, downward, toward the back, or towards the sides? My inclination is upward, but again I've never used a skimmer before.
Also, if you have an AIO, do yours need a skimmer? Do you feel they're necessary on an AIO? All opinions welcome.
Thanks!
