Hi,
Bit of a problem with our water and starting a new 60L tank, would appreciate some help please.
Found that the tap water, which was always soft, is PH 7.5 out of the tap, but degassing down to PH 6.6 with a KH of barely 1dk (just 1drop on Api test kit) and a GH of barely 2.
This moring the tanks pH , with just the substate in, is down to 6.4 by midday and have just tried a new different brand KH test kit with the same results.
Our 3 year old tank with a standard aquarium gravel and sand did hold the PH up to 7.6 before the daily Co2, with a KH of 3 and GH of 5 though that has dropped a bit as the tap water must have been getting softer over the months.
Know that the hardness need to be increased to keep the PH stable, but what is the best way to do that ? We will be using some well soaked wood in this tank.
One other point we cannot quiet understand, if the waters PH is naturally down at 6.4, does that mean there is already 30ppm on C02 or Carbonic Acid in the water, so we don't need to inject CO2 ?
