It definitely isn't terribly high, but for a crustacean, that can put a lot of stress on them.Specific Gravity: 1.025
Temperature: 8.2F
Ammonia: Looks to be 0 - Salifert
Nitrate: 13.1ppm - Hanna
Phosphate: 0.16 - Hanna
pH: 7.97 - Hanna
Alkalinity 7.1dKH - Hanna
I guess that solves the mystery. Nitrate is high and phosphate is super high, or am I not reading this right?
