No holes drilled yet-The hole for your spray head I would use as a drain. The standpipe I would try to get it as close to the wall as possible, drill 1/4” holes in a straight line along its length, point the holes against the wall slightly flowing counter clockwise and use it to feed water in, cap the top of the pipe. Your bait will live all day at least.
Solid advise. The 3/4 inlet side is coming in under pressure filling the tank way faster than a 3/4 gravity drain line can empty it. The rule is every time you go up in a pipe size you increase your volume 3 fold. So for example from a 3/4 line to a 1 inch line is 3 times the volume like the difference between 1 cup of water to 3 cups of water. With the 1 1/2 inch drain your 3/4 inlet source can't overwhelm the drain unless it's clogged.I would go with a lot bigger than 3/4 for a drain pipe.I used 1 1/2" on mine.Mine drains from the top of the tank.

I bet if I ask you how to rig my fishing rod you’ll tell me to buy another rod!
The difference between a master and an apprentice is the master has failed more times than the apprentice has tried.Maybe. Just maybe before buying the tank you bought. You should have asked which tank to buy. But I’ll accept the maroon comment.
