SOS tank emerg. help please :(calgary area

[Brighteyes_13]

sometime during the night my heater blew, woke up this morning to popping noise in the sump. luckily i unplugged it off before reaching in to see it.

it was shorting in the water for anywhere up to 10 hours... im really at a loss.

the only fish i see is my scopas, who is huddled face first in the rockwork breathing heavily, i dont see my clowns or my coral beauty, the lights have been on now for 20 mins. the xenia is slumped over and not fully extended, and the anem is shriveled densely, still responds to light but hasnt reinflated. the skimmer is going beserk, filling the cup every 10 seconds. the only thing still wandering around as if nothings wrong are the inverts... snails and hermits all normal.

salt is mixing for an emergency change, but i dont have any carbon to run. im at a complete loss as to what to do, its a holiday so i dont think i can get any from the store.

somebody help please, i think im loosing the entire tank.
