Crap...I forgot to update this thread...I have 3 nitrate tests, 1 pinpoint monitor and two different brands of traditional test kits. I tested the water with the test kit and it gave me the 35ppm reading. When I tested with the pinpoint monitor I got 22ppm. I re-calibrated the monitor and got 21ppm. We are believing the monitor.
I did that water change yesterday, so I'm going to check the levels in the tank for today, and possibly do a second change tomorrow.
Nitrate levels are definitely the product of some seriously heavy feeding over the weekend, and possibly the death of the powder grey. I know the powder grey was eaten over the course of the 8 hour night, but still 8 hours is a long time.
I'm tired of this though, I just want a nice tank again with fish that thrive and don't die. I think I'm asking too much lately.
