Daily tests: day 31

This morning’s test results were:

  • ammonia: 0 ppm
  • nitrite: 0 ppm

Some of the plants are starting to suffer from the higher temperatures and no light. Given that my first stock will be 9 × 10 mm Danio margaritatus, I expect that they will not produce more than 2 ppm of ammonia per day. So, while for a full stock I would be aiming to see 4-5 ppm of ammonia processed in 12 hours, I will settle for the 2 ppm in 24 hours for now. I will now gradually start dropping the temperature into the 22 °C range and I will start using the lighting. To avoid algae problems, I will also dose ammonia in the evenings from now, instead of the mornings, so that by the time the lights come on, there will not be much ammonia left left.
