Setting up a 16 gallon bowfront tank ----- drill or not to drill

[Amstar]

in the past I had this tank up and it was a nice looking tank until my heater fried everything.

before I had a hang on the back of the tank refugium... this time i am thinking about drilling the tank to set up a sump

the sump would be a 5 galllon tank to fit in the stand

Anyone near dayton drill tanks? I dont want to do it

what size holes? return pump?

Drill. Always the best option. As long as the tank isn't tempered
