This morning’s test results were:
- KH: 12 ° (214.8 ppm)
- GH: 18 ° (322.2 ppm)
- ammonia: 3-4 ppm
- nitrite: 0.1 ppm
- nitrate: 1-4 ppm
- pH: 8.2-8.3
The results show an increase in the KH and pH, the two are related and most likely caused by the sand. This should not be a problem as both should drop with the addition of plants and wood.
I am not completely certain on the changes in nitrite and nitrate, but neither looks as clearly blue or yellow as they did in every previous test. Or maybe I am just getting overenthusiastic.. tomorrow’s results should show whether there really is a change in either.
The temperature is mildly fluctuating between 28 and 28.5 °C, which is not unusual, and I have had to top up with 5 litres of water, due to evaporation, because I am currently not using the coverglass (it is on another aquarium).
