How to unlock the Deep Sixed achievement in Resident Evil - Definitive Guide
After you have drained the water in the Aqua Ring you will have to return to the lower section of the Area to get the Gallery Key.
Run past the small Shark and past the dormant big Shark at the far end of the room and climb on the ledge.
Soon as you try to grab the Key Neptune awakens.
All you have to do is push the green box into the water and pull the lever on your left.
This will fry Neptune and unlock the Achievement

Just push the large white box from the platform into the shallow water below and it'll create an electrical current through the water. Flip the switch, fry Neptune & the trophy is yours!
You first encounter Mother Neptune in the Shark Tank area of the Residence; you attempt to drain the water and she’ll attack the glass making this a timed event. First you’ll need to deactivate the safety and attempt to close the shutters, the shutters will jam. Move into the hallway to see three valves, one of these valves will restore pressure to shutters. If you don’t know which, there is a white board on the ground telling you what valve to activate. After restoring pressure to the shutters; again deactivate the safety and close the shutters, then drain the water. Exit the control room into the area and approach the platform the big shark is near.
Now here is where things can vary; you can either use bullets to put the Shark down or use electricity to do so, thus saving you bullets. Attempt to grab the glowing icon and watch it fall into the water while the shark thrashes about. Push the small console into the water next to Neptune. Now turn left and flip the level to activate the power source and kill Neptune without wasting a bullet. You’ll earn this trophy once the shark is dead. It should be noted you can actually grab the key without being killed, but it is tricky to do and thus killing the shark is the best method. At the same time, you’re free to kill Neptune via electricity and not lock yourself out from earning CQC FTW.
Note: This achievement is technically missable but is hard to do. As you actually have to know the "shortcut" which would enable you to run passed the shark without getting gobbled up.
After draining the Aqua Ring, you will have to get the Art Gallery Key which is located in the area where the Neptunes were swimming. Mother Neptune is chilling in a pool of water and won't move as you walk passed it. Climb up the walkway and examine the key, where it will suddenly knock the key into the water with it and become hostile. Do not enter the water as you will likely die, instead push the metal box nearby into the water and flip the switch on your left to fry it. After the Shark dies, the achievement unlocks and the water's safe to enter without being electrocuted.
You can also kill the Mother Neptune with firearms, though this is a waste of ammo (unless you have the Infinite Rocket Launcher).
