It's a 55gal and I just listed the livestock above. All the other info is in my sig in the first post. The kit just gives the three ranges low-safe-high. High is from 2.9-3.6 and by color it seems at the higher end. It is a Red Sea kit and the buffer doesn't say what kind of buffer it is, just "Buff." The Tang is now upright but its breathing a lot faster than when it was on its side.
