Brand new and more than a little confused.

Can a tank be drilled while partially full ( say half full of water ) or will there be filings and bits falling into the water? I dont have a drill press can i use a hand drill?

Using an overflow box that hangs on is askin fir trouble I had one and it needs daily maintenance and your walking on needles on your sleep wondering if it's working right , not overly safe for power outages I don't have much faith in those vacuums.

No, it needs to be empty. If you have livestock already, it's too late, as there is always a risk of it cracking, and that would suck if you have stuff in it.

for the price of an overflow box you can buy a small tank thats drilled ive seen tanks for less than a hundred bucks and still a decent size
