75 gallon community tank with praecox rainbows, ottos and two columbian snowball plecos, gold lazer corys and two rainbow stiphodon gobys. Everything was ticking like a clock with no issues for months.
I moved over the past weekend and every fish made it through the move healthy. My water at my new apartment has a blue-ish tone to it.
This morning I awoke to finding 3 rainbows dead, 2 corys dead, 1 snowball pleco dead and one goby dead.
My parameters are: 10 Nitrate, 1 Nitrite, 300?! Hardness, 40 KH, 6.4 ish PH. 0 Chlorine.
I did a 10 gallon water change before I left for work but I'm afraid my entire tank is going to be collapsed by the time I get home. Recommendations?
