HELP!

[JurisHP]

I am freaking-out. Yesterday I awoke to a dead wrasse. Ok that happens every so often so I just chalked it up to dying a natural death. This AM I awoke to my Powder Blue, Orange Shoulder, Gem and Purple all dead and others about to be dead. Devastated.

My parameters are as follows:

Salt: 35
Temp: 78.8
pH: 8.01
dKH: 8.92
Ca:L 465
Mg: 1209

The remaining fish look "cloudy"...not Ich...the only new thing I have done recently is turn back on my Ca reactor after having it off for about 2 weeks.

Thoughts?

Look very closely at any remaining fish. Either there is/was velvet or lack of oxygen from high ammonia and/or nitrate.
What is your ammonia-nitrate-ph and what test kits are you using ?
Any stray voltage? (placing a finger in tank or sump, you may feel a small jolt)
Any signs of rapid breathing or loss of appetite Prior to losses ?

My Nitrates are OFF THE CHARTS HIGH. I don't know why! The ONLY thing I recently did was leave my cCa Rx off for 2 weeks and then turned it back on (pumps only--not CO2 yet)....could Nitrates have risen exponentially in the reactor and then dumped into the DT when I turned it back on the other day?

It was off for 2 weeks. Then turned back on? Did you drain the water first? Almost sounds to me like hydrogen sulfide poisoning.

 

[JurisHP]

Yes … off for 2 weeks and no, I didn’t drain the water before turning it back on. Is that the culprit?
