| I can only report what the Tetra kit colorimetric assays reveal, which is not the same as having a complete water analysis done by a lab. In regard to ammonia and nitrite the readings were zero. The nitrate was 12.5 mg/l or less. For the record, I spend a lot of time working on the pond attempting to provide the best water I can for the fish, which is what inspired my original question regarding GH. |
