When I came into work today I noticed one of my Sterbai Corys has a white spot on them. This is my very first aquarium. It has been set up for five weeks, the inhabitants are 4 Sterbai Corys and 3 Nerite snails; they have been in the tank a little over 2 weeks now. I did a cleaning and 15-20% water change on Saturday.
Ammonia 0
Nitirite 0
Nitrate 0-10
KH ~100
GH 300+
PH ~7.6
using the coop test strips. The only change in parameters is the temp jumped up to 82 over the weekend(didn't make any changes to the settings). Usually it's around 76. This is the second time I've had the temp jump with this heater. (is my heater bad, or are all heaters bad?).
I thought maybe it was ich, but doing some research it doesn't look like it, and it seems ich shouldn't be viable when the temps are above 80.
