Well it has no Co2, it runs around 75 degrees from ambient temperature, no heater. Fugray light, turtle 501 filter using the spray bar. Lights are on a timer, recently removed 2 hours from the middle of the light cycle to combat algae. I have sand capped eco complete as substrate.
14 gallon tall tank, with 6 long finned zebra danios.
I think it was just ammonia but even after the waterchange fish still died.
Reading was on alert on my seachem ammonia alert, and thats at .05ppm
After waterchange it was in the safe range, and I am looking at the tank now and its back on alert.
