We tested the water again today for pH, nitrates, nitrites, and ammonia. The levels were:
pH: 8.8
Nitrates: 10 ppm
Nitrites: 0 ppm
Ammonia: .25 ppm
The nitrate and nitrite levels are in the correct range because nitrates should be below 40 ppm and nitrites should be around 0 ppm. The problem we are still having even after adding chemicals that are suppose to work is that the pH and ammonia levels are too high. The pH should be around 6-7 and it at 8.8 and the ammonia level is at .25 ppm and it should be at 0 ppm. I added some pH down to try and lower the amount of pH in the water. I would have added more ammonia neutralizer but it says to not add to much per week. We will continue to monitor these levels in hopes that the will balance out and our plants will grow more.
