Two of my fish died overnight?

[r.reefer]

Hi guys, I woke up this morning to find my coral beauty angelfish and my six line wrasse dead in my tank. I feel like it's not a coincidence, but now I'm just trying to figure out what happened. The only thing different is that when I tried to plug my filter back in last night, it wouldn't turn on. Could lack of oxygen be the reason? I am about to leave to go get a new filter ASAP. I have two clownfish as well who look like they're breathing fast. Any help would be appreciated. It's a 50g mixed reef tank. I just tested the water yesterday, and everything seemed to be okay, a couple parameters were a little high but nothing that hasn't happened before.

Was ammonia high?

Is your filter the only source of water movement in the tank? If so, then lack of oxygen in the water could definitely explain the deaths. Clownfish are a bit more hardy which could also explain why they survived.

How soon can you get a new filter up and running on the tank? Do you have an air stone or even a cheap powerhead you could stick in the water to get some aeration? If not, at a minimum you can get a cup/jug and pull some water from the tank and pour it back in a few times to try and oxygenate the water before you go get a new filter/pump.

White light pics and a short video of remaining fish. Any new additions to the tank?

@Jay Hemdal @vetteguy53081 can help once you post the pics / video.

Dead filter….
-Rise in ammonia
-Lack of water movement/low oxygen
Disease such as flukes, velvet

**as mentioned, pics will be helpful
What is your ammonia-nitrate-ph-salinity- water temperature?

WHAT TEST KITS ARE YOU USING?
Signs of heavy breathing?
Lethargic behavior?

Did the angel and the wrasse die with their mouths fixed open?
While low oxygen can certainly kill fish, if the tank had some other means of circulation/aeration, that may not be the issue. Once filtration is restored, the clownfish should return to normal breathing in an hour or so. If they don't, then there may be another issue going on here.

I replaced the filter using the old cartridge, and within an hour the clownfish were breathing normally. i have 2 power heads, but maybe they’re too far below the surface for good aeration? Not sure!!

clownfish were fine once filter was replaced!

Was using RedSea test kits. Ammonia was 0-0.2 (RedSea indicator colors are kind of hard to read), nitrate around 5 (currently dosing a reducer), pH around 8.2, salinity 35, temp at 78. There was heavy breathing from the clownfish, but this stopped once i replaced filter!!
