My water quality
Thanks to Dano for showing me where to look for the color charts to use with my test kit I have the following results in my two 10 gallon tanks:
ammonia 0-0.25 ppm
nitrite 1.0 ppm
nitrate 10-20 ppm (color was right in the middle of the two listed on the charts)
the test kit isn't new but the chemicals don't expire until next year according to the mfg. web site (lot number on the bottles shows them being made in 2005).
I think I am doing something right.
Thank you again Dano for showing me where to look.
