Test results and maintenance update

Almost two weeks ago, on Friday when I collected the loaches, I did a 20 litre water change on the tank because I wanted to acclimatise the loaches directly to the water they would have in the end, so I used the water from the 60 litre for the quarantine tank. The test results for the water from the 60 litre before the water change were (on day 113):

  • KH: 7 ° (125 ppm)
  • GH: 19 ° (339 ppm)
  • ammonia: 0 ppm
  • nitrite: 0 ppm
  • nitrate: 20 ppm
  • pH: 7.8

And today (day 124):

  • KH: 8 ° (143 ppm)
  • GH: 18 ° (321 ppm)
  • ammonia: 0 ppm
  • nitrite: 0 ppm
  • nitrate: 20 ppm
  • pH: 7.8

The temperature has been steady at 20 °C, which is perfect for these fish and fits in with the recommendation of the breeder from whom I bought them.

Following these tests, I performed an 8 litre water change (with the old water going into the quarantine aquarium that contains the loaches) and finished off by wiping the glass on the outside.

Current maintenance schedule consists of cleaning the glass and pruning the plants once per week. While normally I would recommend weekly water changes to beginners, in a well balanced aquarium such as this (which is lightly stocked and is planted enough that individual plants can not be counted) which does not contain young fish and where the fish are not overfed, the water changes are not as important because the plants can maintain the water quality. For the moment, I do water changes when I feel that they are needed or need water for the unplanted quarantine aquarium.
