a friend of mine just purchased a wet/dry unit and the holes for the fittings are wrong. to small. so how could we drill out the holes for the correct size. is there any special bit that we need to use? or any tips you guys can give. thanx alot.
I would use a hole saw. put a piece if wood underneath tank to support the plexi and allow the center bit to dig into something dont push to hard let the bit do the work.
