I'm new to reef tanks and I am a little confused about hole sizes. I've spent about 6 hours looking for answers, but I am still confused.
I'm setting up a 40 Gallon Breeder tank with a 20G sump. I'd like to do the herbie overflow and have two holes drilled behind an overflow box on one side of the tank, and the return on the other side of the tank. From what I have read, most people usually make the return smaller in diameter. Since I will probably only be using the drill bits for one tank, I'd like to only buy 1 drill bit.
So.. Could I drill all three holes to fit 1" bulkheads? Would this be enough drain or even work with herbie? Or should I drill all three holes to fit 1.5" bulkheads and use a reducer on the return.
Thanks!
