Nitrates

We are talking in the 80+ range when we first got home, then after a water change, we are down to 40-60ish.

Its a salifert test kit. I sterilize them before and after I use them, and I'm pretty good for the shaking part. I'm planning on picking up a new kit this morniing after class I'm wondering if its expired since there is no date on it.

After this little incident I'm seriously considering tomorrow's morning for building a refugium.
