All corals closed up and new animals dying

And what are the phosphate levels you are aiming for? And how do you raise the phosphates when they are to low?

I have my phosphates at .05 to .1, I usually have the opposite wehere I have to remove phosphates. If I'm not paying attention and I take it all the phosphates out on accident bad things happen. If I shut my skimmer off and turn my fuge light off for a day it usually rises within a day or so. You can buy phosphates to dose if you think you need too

Oke thank you! In that case I will get a bottle PO4+ soon to raise it to around 0.05-0.1 and see if it does the trick.

It definitely wont hurt anything just take it slow and dont overshoot!

Yesterday I moved my duncan coral from my 20g to my 10g.

This is how it looked in my 20g before moving.

This is how it was in the 10g right after moving it.

This is how it looks now 24 hour later.

When I move the corals to the other tank they recover really fast!
Does this looks like something caused by low phosphates?

Honestly its really hard to tell.maybe its phosphates quite possibly its something else. I would inspect your power heads closely for cracks and make sure one isn't leaking electricity. Ive had this issue before. Its odd that it all happened at once. Usually low phosphates take a while too cause coral issues and some times its fast depending on what the corals are acclimated to.
If you had them at .80 for 10 months realize that OMG!! I need to do something and drop it to zero with some chemical the next day everything would be ticked. Have you started carbon dosing???? Have you added a cool shiny rock lol. Was there anything you did before this happened. Lights could be the problem, have you changed the photo cycle recently? switch your lights and see what happens?? Just trying to throw ideas out there
