    CO2

    I live on a farm near Napier. My (70 litre) abundantly planted monobloc tank contains soft rainwater, mixed with spring water (conductivity 600 microSiemens). My diy CO2 system seems to work well, most of the plants just about double in size every 3-4 weeks. The plants prevent nitrites (always nil despite the occasional fish casualty) and help stabilize the pH which is constantly 7.1. --Hans--
  2. :lol: I would prefer not to use fluoridated water, it is after all a poisonous chemical. Other chemicals such as ammonium sulfate have to be added to the water supply as well in order to stabilize the fluoride, etc. etc. Hastings water is I believe quite hard. Living on a farm I use rainwater mixed with a bit of spring water which does the trick. cheers, Hans
