I was thinking the same! 40 gallon breeder and a 20 halong Long refugiumWelcome @Anthony Paun to R2R. Definitely a sump\refugium....the largest tank you can fit. Take advantage of the dollar -a-gallon sales at Petco. As far as an overflow, there are a number of choices. Definitely drill the tank.......Glass-Holes is an example that comes with the drill bit.
