tank cloudy?

[Jfaiii]

So I was gone all day and came home to a cloudy tank. I did all the tests that I have and came up with nothing wrong that I can tell

PH: 8.2
Temp: depending on the day 80.8-82.7 currently 80.9
nitrite: 0
nitrate:0
Phosphate: 0
ammonia: 0
calcium: 430
DKH: 10
salinity: 1.026

The only new thing in the tank is a UV sterilizer that has been in for a week now.

I am confused as to what may have caused this. Could it be that something died, maybe a snail, hermit crab, or lettuce sea slug? everything else in the tank is alive and accounted for. Also all my coral are fully open and the fish are active even though it is cloudy.

Any idea what may have happened? I'm guessing that something small died but I have never had it cloud up the tank like this.

If something died your nitrates would be elevated, How do your corals look?

Bacterial bloom?

I thought the nitrates would be up too but all my corals looked fine and open before the lights turned off a little bit ago. All the fish were acting fine also.

Bacterial bloom?

+1

If something died and a bloom occurred wouldn't that hide the nitrates?

 

[Jfaiii]

if it is a bloom is that problematic?

Shouldn't be, your tank is self adjusting.
