On the 9/03/2013 we measured the temperature and got a reading of 23 degrees C and the temperature of the room was 18 degrees C. We also measured the pH of the water for the first time, when we put the drops in our water it turned a dark green colour which indicates that the pH of the water was 7.
On the 10/03/2013 we measured the temperature of our aqua zone as 22 degrees C and we took the pH of the water and it turned the same dark green which tells us that the pH was 7 again.
On the 12/03/2013 we took our final readings, the temperature of the aqua zone was 20 degrees C and the water turned a very dark green colour showing that the pH of the water was 9.
