So sorry to hear that! Did your tank lose power or heater malfunction?

 

[T-J]

Nothing about those numbers would kill fish that fast.
Can you post pictures of your deceased fish? Sometimes some of the experts here can look at them and see if there was any fish disease.

Ammonia can harm fish but those numbers can’t unless it’s a small tank. Also ammonia doesn’t rise that fast, it usually takes a day if it’s stable with parameters, if it’s new it will spike fast however an old tank won’t have ammonia spike fast unless something is decaying in the tank.

Fish cannot die that fast without:

A: equipment failure

B: extreme chemical issue (someone spilled something into the tank, you did a big water change wrong, used windex on tank, high overdose of some meds or other chemical)

C: tank not cycled, not enough surface agitation by an extreme amount, or overstocked (not enough oxygen (even then a bit of a stretch) or too much ammonia)

D: very poisonous creature getting torn to shreds

That's 2 of the fish it's 132l was 2 clowns today one springer damsel one blenny one cardinal and one mandarin tank is been running 10 months only thing I added to tank yesterday was some beighwell razor for hair algae but I added less than the recommende amount to be safe could it be that

Maybe it effected the oxygen in the water? -Raven

did you clean your glass with or have any chance other of cleaning chemicals entering the tank? Do you have any poisonous sea creatures that could have gotten sucked into the wave-maker?

Nothing that I can see of, and if you dozed a smaller amount than recommended then that couldn’t be it… Some fish deaths are just mysteries however I see a bit of a torn fin on the clown. I don’t see how O2 in the water could be affected either. The torn fin may be from asserting dominance with the other guy.

something must of gotten into your tank for this to happen

It could harm the fish, but I don't think killed them all in a few hours

you said you had nopox in another thread, thats a chemical filter. Do you have any other chemicals in the tank?

 

[ubiq]

Got kids?

 

[twiggy]

No kids haven't cleaned the front of tank apart from with a magnet I haven't dosed no pox since I had that issue a few months ago they have all been fine since the fish were on the bottom
And one of the crabs was on it maybe that why damaged fin nothing in the wave maker

How big tank, how much added?
Get a picture of what your trying to kill under white light.
I've got a suspicion.

Do you think it’s a toxic species of algae?

only from this pic views, looks kind of fish disease called brooklynella, it looks similar to ich but fish dying much quicker than ich, mostly just overnight. rodi water bath or copper base solution works but won help a lot if the disease went deeper. good luck man!
