Need input on overflow hole size

[StirCrazy]

Ken, Call up Seastar and ask what it would cost to get your tank drilled and a 1.5" bulkhead put on. I just did this for my 2 little tanks as no one in town has a hole saw bigenuf for a 1.5" bulkhead. Brad mentioned the "glass smith" they were talking about getting some bigger ones but last time I checked they still had not gotten them in, but give them a call and ask if they have any holesaw sizes over 2".

hope that helped.
