Crashed tank

[jimmyisfishing1101]

I was on a road trip for 2 weeks and just arrived home and I came home to 7 dead corals and bubble algae all over the tank. HELP!

I removed all the dead coral before the photo

Need more information about your tank

Parameters?
Equipment failure?
Anything you have added recently?
Were lights and everything working properly on your tank when you left and when you got home?
CUC?

I would do water change, test your parameters and start again. Try to figure out what went wrong

Salinity 37 ppms when I got home which I found strange cause I have an ato and left the tank at 35 ppm

Amonia 0-1ppm
Nitrites 7ppm
Nitrate 15ppm

Haven’t test calcium or akalinty yet

I don’t think there was equipment failure

I added a new zoa and some
more snails and hermits before i left
I have 8 nassarius and 2 meat eaters

My lights are working fine

Being that it looks like a pretty new system stability probably just not there to begin with. A more telling sign would be what your phosphates are. If you’re running any mechanical filtration such as filter floss/socks over that period of time it can become clogged up and will restrict your water flow to where your ATO keeps filling the main tank or your sump at an unnecessary rate. Which it looks like you have a HOB, and after two weeks, I’m sure that mechanical filter was plugging up and turning into a biohazard lol

Were there any power failures while you were away? Was someone home while you were away? Anyone feeding the fish? Ammonia range of 0 to 1 is a huge range, what test kit is it? Was the tank overfed? I don't see bubble algae in the tank.

IMO a tank should easily be able to last a 2 week vacation on its own.

I see what looks like Dinos or cyano. I’ll bet phosphates bottomed out.

Tank looks pretty new.
How long has the tank been cycled?
How long was it cycled before adding corals?

It’s been cycled 3 months
Coral after one month

People always say don’t do anything different to your tank before going on a trip/vacation
