Help please, tank crashing, I'm bawling...

[Tabbers920]

Please help, we were away for 5 days, my dad fed the tank and changed filter socks, 3 hours from home and he tells me a fish died.. (fairy wrasse)
I get home and it's a coral graveyard.
My toadstool, hammers, torch, Octospawn, frogspawn, finger leather, ricordea, blasto, acan, the list goes on.
There's small bubbles on the algae on the back wall, so I wonder if I have dinos!?
Then I see the water is 90 degrees!
The thermometer popped out of the water.
I did a 6 gallon water change, floated ice. Temp is now 85. (45 gallon plus sump)

Salt 1.025
TEMP 90 !!
Ph 8.2
Amm .5 (fish died too, so obv)
Phosphate .04
NitRATE 5
Nitrite 0
Alk 8.8
Ca 480

I couldn't change too much water to not shock them by changing temp too fast. Ugh.

Thoughts on dinos? Was the only issue the temp. Also lost Herbie our skunk shrimp :(

What do I do now?

Pics attached. After and before, and curious what's growing under the rock here too??

Temp was most likely the culprit. Get yourself a heater controller. I think it's the most important thing you can have.

It's your temp all day long unfortunately.

If nearly all is dead throw the living in a bucket with new salt a heater and a small circulation pump.

Buy you time on the display.

Heater controller and with this hot weather get a fan to clip on it to blow cool air helps a lot.

O man. So sorry. Get that temp down.
My fish tank will be alone for 3 days this coming friday. Im a nervious wreck.

But watch ur temp

Sorry for the loss. I don't see anything in the picture that jumps out to me as dinos. Having redundancy for a heater is a must. Using a inkbird with a heater that has a built in thermostat is an easy cheap way to have at least 2 levels of protection.

The only thing to do is to fix it to where it can't happen again and then start restocking the tank. Unless it causes you to leave the hobby, which if you go that route I'd encourage you to wait a few days before making a decision. I had a tank crash and I was about to give up, but I didn't and my tank is more stable and healthy now than it ever was before the crash.

EDIT- I would personally just let the temp of the water fall the rest of the way on its own.

Aquarium controller is what comes to mind

I have a nice heater controller, the thermometer that goes in the display came out of the water. Causing the heater in the sump to work overtime. I should have had a $2 thermometer stuck to the side of the DT. :(

Or have the probe somewhere somehow where it wont pop out.

My finnex 800 dial analogs have suction cups on the probes that become useless eventually lol.
