Tank getting drilled this weekend...

[Flaxon-Waxon]

I am thinking 3 holes per someone's advice on this forum and wanted to see what everyone had to say. It looks like I may drill the back of the tank a couple inches below the water line, and was thinking (2) 1-3/8" holes on far left and far right of the back glass, and (1) 1/2" hole in the center but still a couple inches down from water line, for the return.

What's everyone's thoughts? Do I need 3 holes? Should the return be 1/2" or should I make it the same size as the others?

Thanks!

Usually 3/4" or maybe (maybe) 1". Really depends on the flow your looking for. If youre planning on 1800,2400,3600 gph then you may wanna look at 1". Anything lower and id do 3/4
