After filling I had a small leak on the pump and that was it.
Some of the highlights of the plumbing: This tank has 3 overflows, one internal surface overflow, typical overflow that skims the surface water and drains to the sump. I also added two midlevel external overflows that draw water from the lower/mid level of the tank. I did this because this is a used tank and it had 5 one inch holes in the back glass panel! I made two of the holes returns and the other three are for drains. You can never have too much drain capacity. I have three 1" drains going to a 2" main drain that goes to the filter sock. (pics below). Very simple to set up.
I'm using a filter sock in the sump, first time using a filter sock. It was really easy to set up. I got a 8" filter sock and holder and mounted it so the filter sock is at the sumps operating water level. I didn't want the sock to high because if it clogs up I want the excess water to overflow into the sump and not my living room. I'm optimistic about this filter sock method, it looks super easy to change out (I bought an extra sock). When it gets dirty I will replace it and work out a cleaning plan for the old sock.

From now on I'm using controllers for the heaters on every tank! Sucks!
