Phil's new 46 gallon frag tank

[Phil]

ok filled the tank with water and onle 1 leak!?!?!?! it was a union missing a rubber oring i found it on the floor and replaced it and no more leak

Now problem #1

my overflow is too small for a herbie in 1 1/2

so im gonna try 1 1/4 and if that wont fit im going to use 1"
any suggestions are welcome.

problem # 2

now i know this was going to happen so i didnt glue the drain line in.


Whats the best way to make it quiet and less splashing? put a 90 half in the water or run the plumbing down to the bottom on the sump?
