I'm with you Tony on the probe. Keith brought his over and tested my water and it was out of this world!!! I don't even bother with testing the water anymore, it is just frustrating. My fish let me know when they need a water change, but now that the tank is a year old we don;t have any issues at all... touch wood.

For example, I get about 5ppm NO3 readings using both Elos and Salifert .. which suggested to me that maybe my NO3 was around 5ppm, but when I use the probe it tells a much different story (30ppm).
So I'm not disputing your 5ppm, it may well be that, but I'm just curious what readings I'd get on different water.
