Notes
The ammonia levels were tested using both a low range Hanna checker and a high range Hanna checker recently given to us by Thames 21. The high range Hanna checker showed a reading of 0.43, so both had a very similar reading. This reading for ammonia was by far the lowest we have ever had and was considered Very Good on the instruction notes, which felt very special to us.
We also tested the phosphates using both a low range and high range Hanna checker, also recently given to us by Thames 21. However we didn't get a reading from the high range Hanna checker but a 00 on the screen, so something had gone awry, and there wasn't time to do it again. Better luck next time.
