90 Fresh---->Salt Drilling Tank?

[monocus]

i drill mine at the bottom,use a stockman standpipe,and make my own overflow box using large pvc drilled and slotted

[doch]

I picked up glass hole saws and did the drilling myself. (gl*******s.com) Very Easy. Go VERY slow as you'll end up chipping the glasss otherwise... which I did. To compensate I put the rubber bulkhead gasket on the inside of the tank where the glass is smooth.
