plumbing advice needed

[habs247]

Thanks everyone. Really appreciate it.

Reefgirl - Any pics of your setups would be very helpful. Actually, everyone (but reefgirl offered).

I should note - I'm limited to the three holes that are drilled since the tank is coming tonight. Hope I didn't make a mistake - certainly no double 1" or 1.5" holes here!

Hoping my plumbing is quiet as it's in the family room. Any suggestions on how to pipe return into the main tank quietly are appreciated!
