I just set up my GEOsystem South American aquarium and seem to be having problems stabilizing my pH, am I doing something wrong?
The stability of pH is related to KH (carbonate hardness) as well as your local water conditions. If your local water is very soft you can expect a temporary increase in pH as the gravel may impart some buffers to your water chemistry, thereby causing a rather quick increase in pH. As the aquarium matures biofilms will become more widely spread on all inner aquarium surfaces, including the gravel, this will in effect help to subdue any potential effects the gravel may impart on water chemistry. It is important to thoroughly rinse any natural gravel and employ a pH and KH test kit to accurately adjust values with the appropriate Nutrafin pH Adjust product to within the recommended range. The use of Fluval Granulated Peat and a CO2 system is also recommended to help control and maintain the desired pH and KH levels. 2. I recently set up a GEOsystem Asian Loach, Gourami and Danio aquarium, exactly as the Guide instructed. I thought these fish were compatible but some of the Gouramis chase
