Drain it and drill another drain hole for emergency which sits higher than the current one.

Picked up an Ocean Revive Artic T247 today, needless to say it's dialed WAY down at 10% White 20% Blue. Made a frag rack and have an occupant testing the waters! Exciting! The rest of the frags will go in tomorrow if all is well.

Just put it in that's why it's not open yet. I'll update tomorrow with how it looks.

Looks like I should have done a 3/4 overflow. At least I know for next time. The overflow is back to the original boring open ended pvc, and lll get a glass holes overflow skimmer to keep snail's out.

You should make an overflow box drill another hole for a 3/4 bulkhead next to the current drain and make the 3/4" an emergency drain and add a ball or gate valve to the half inch drain and run it at a full siphon. it would be super easy to attach an acrylic internal overflow box being that they would both be acrylic (weldon 4 solvent). that how I would do it, its called a herbie drain and it would give you a completely silent drain. hope this helps:D
