Tank seems to be dying...

Ph 8.4 ammonia 0 nitrite 0 nitrate 0

Year Established 27.5gal

Tankmates two frostbite clownfish now 2 chromis fire fish dragon goby yellow tang (to get transferred to my 180 when it's up and running) and a cubicus no fish I am holding for a friend. I added a lot of Xenia some blue ridge coral some green pascoma and mushrooms from a friends tank he was shutting down. This morning lost one of the previous 3 green chromis and the clowns and other two green chromis are acting crazy and coral doesn't look good my montipora cap was looking great and bleached over night. Rbta looks fine and the other fish outside the clowns and chromis look good. Did a 20% wc even though Params didn't move. Put a lot of carbon in hob and now don't know what to do. Is it the boxfish?

Hard to tell. Sometimes, impossible. I've had a tank die on me, never did figure out exactly what happened.

1'st suggestion, get new test kits, or just take a sample to your best LFS. The test kits we use are notorious for false results... old reagents, bad lighting, could be lots of factors skewing a test kit.

2nd suggestion, chemical poisoning. Air fresheners and household cleaning chemicals getting into a tank is a real problem for many, and may well be the reason for the crash I had.

Boxfish are fairly sensitive to parasites. Could be that moving him into your system stressed him out enough for an outbreak.

Is the tank on a GFCI?
Have you tested for a faulty pump/heater,etc..

Or maybe heater got stuck on? (happens often)

Alkalinity test results?
Salinity?

[TokiHacker]

Salinity 1.026 alk was 10 last time I checked yesterday

[TokiHacker]

Water temp was fine and all is running properly

Lfs says all is perfect except calcium at 400

Returned boxfish to lfs told my friend to go get him in not holding him anymore

Was gonna say, it's probably the box fish. When they are stressed they release toxins which will kill other fish and even themselves. And apparently they stress over everything.

That's the only thing I could rule today....

[TokiHacker]

Loaded the filters up with carbon.... now water changes and wait

[TokiHacker]

got rid of boxfish and clowns look better but mushrooms look like crap.... will do another wc tonight and check. In morrning

[TokiHacker]

Anything else anyone can think of??

[Sk8r]

RUn carbon and run POlyFilter if you've got it. Either can absorb organics, and this toxin is an organic. 30% water change. And then just hope.

[TokiHacker]

I just did another wc running lots of carbon and poly skimmer is wet skimming

[TokiHacker]

Fish made it through the night but the coral is not looking good

[TokiHacker]

Did another 25% wc... don't really know what to do now

[Shwimy]

Hows the tank doing? did it pull through

[TokiHacker]

Yes!! Sorry.

I was running this system w/out a skimmer (had a PS1 in it and it ****ed me off). Went with a coral life and that solved my issues. the boxfish did kill a few things sadly... but everything now is prospering (except my fingerleather now finicky pain in the ...) but everything is back to normal!
