Which would make tank crash??

[CurtnStac]

My tank is an AIO Innovative Marine sr80. Corals are mainly softies and euphyllia so I run higher nutrients. 2 weeks ago the skimmer (tunze 9004) overflowed and about half a cup of gunk spilled back into tank. Since then my tank has completely crashed. Most of my hammer coral has receded and died, bta are closed and lost color, mushrooms have melted away, and lost 2 fish.
Did an icp test right after skimmer overflowed. Which of these results would cause the crash?? I know phosphates are super elevated but would that kill fish??
Skimmer also stopped working after it overflowed. Would that cause low oxygen and kill corals? But I do have 4 return nozzles at the surface.... Any help is appreciated!!!

I'm wondering if you don't have stray voltage from skimmer failure. I've had skimmers overflow back into tank with ZERO effects (maybe cloudy conditions temporarily) Something else is awry.

Tested for voltage when this started and found about 6 volts going through the tank. Quick added a grounding probe so now there's 0 volts but problem still persists. Thanks for the reply though!

Have you done any water changes? If not; I would certainly suggest that to help you re-balance the nutrients in the tank, which should help the corals recover.

Nothing in the list of elements you listed should have caused fish loss, that I know of. Have you checked salinity and temperature lately?

I agree with a healthy water change for starters. But 6 volts going through tank for how long? Basically your inhabitants were being fried slowly and it took "X" amount of time to notice. You know the saying "Nothing Good Happens Quickly in a Reef Tank". Glad you installed ground probe.

I have done lots of water changes, specially right after the skimmer overflowed. I'm also running good carbon and poly pads.
Thought my refractometer was bad even though I calibrated it but icp test shows salinity in range so my refractometer is good. Temp is controlled by apex and I have 2 other thermometers in to verify.

No clue how long the volts were going through the tank. Didn't check till things got bad. 2 fish died after I grounded the tank so wouldn't things slowly get better after grounding?

Here's the really weird thing... Through all this crash my cleaner shrimp is perfectly fine. I must have a super shrimp lol

Depends on how long they were exposed to voltage. Your cleaner shrimp probably glows in the dark now...lol

6 volts will do nothing to your fish or your corals if it was 20/30 volts then yes as those voltages will start to change the chemical makeup of the water.

6 volts is alot to expose fish & corals to! To you or me 6 volts is nothing but to fish and corals it's life threatening.

You have any prove for this,if you have a high amp with your voltage then yes a low amps no.

Yea here's proof - take a 9 volt battery and put in your sump & tell me what happens? It's low amps... I guarantee the results aren't going to be pretty!

 

[Mical]

On top of that, these are tiny creatures and you can't possibly tell me they are NOT going to be affected by 6 volts high or low voltage.

I think that you should read up on the studies carried out about the effects of electricity on marine life before you give stupid answers

From this point on I think I'll just ignore your responses & posts because you're the one with limited knowledge

Allllrighty-back on track from bickering.
I’m in the “in probably slowly whittled them away” camp.

Regardless of that-i highly doubt its your skimmer cup. I’ve dumped plenty back in unless there was an ammonia spike from something decaying in your skimmate. How long had it been since you last emptied it? Also, was this change an immediate overnight? Like corals were fine Monday and Tuesday the tank crashed? Or was it gradual?

 

[ahiggins]

To be honest-looking at your numbers-even the low numbers to high numbers in a short time could have affected something. But that would have been “things were fine last night but awful today” type of change.

Either way, you had a gorgeous reef and I’m sorry it happened

You mentioned that the skimmer stopped running. The water tests show some extra metals in there. Did you pull apart the pump to make sure it did not swell or crack and leak nasties? A cupful of skimmate really should not crash a tank; I frequently dump mine back when the system gets lean on nutrient.

An overheated and consequently exposed magnet drive can do bad things.

The poly filter shows no colors? Were there other pages on that water test?

SO I guess I would
a) remove the pump, inspect and replace
b) double down on the real thing poly filters
c) run carbon (GAC)
d) change more water

It happened overnight. The skimmer overflowed late in the evening. When lights came on the next day everything was closed up and ticked. Did water changes and ran carbon but things just got worse over the course of a week. And now after almost 2 weeks later things still aren't looking any better.

I did remove the skimmer about a week ago but haven't inspected it yet.
Poly pads were just really brown after 5 days.
Running good carbon since the beginning of this.
