Sump size for 180

[CarpCharacin]

76G is like $90 on the $1/gallon sale. I bought 2 for sumps. Just fyi, they are NOT drillable......$99 lesson.

I'm probably going to get a 55, and I'm not planning on drilling it.

What size of tank should I use for my 180 gallon sump? Should I use a 40 gallon breeder, or a 55?

The LFS store near me had Seapora 60 gallon tanks 4ft x 15" and works well as a sump.

Size is not as important as the set up

a well set up 55 will out do a poorly planned 75
