Hey guys! I am finally building my system but I feel a little bit nervous. I want to do this right! I have a 210 gal wallmount and for my sump I have two tanks. 1x 75 gal. and a 30 gal. Will this be enough or should I go with a bigger sump? Also what size should I drill my 210 gal. ?

my size is...

my tank is 220 gal and my sump is a 40 gal. That should be enough. Even if the power goes out, my sump can handle the overflow

I am using a 75g for a sump on the 210 I am setting up right now. My tank is an aga megaflow, and I also drilled it for a closed loop. 2-1.5" bulk heads to feed the pump, and 4-1" returns.
