NORMAL pH
The pH of water in the ocean is around 8.1. This is also the recommended pH of a marine aquarium, with levels slightly above or below this value considered acceptable. This happens as a result of the carbonate hardness value of sea water, which is about 125ppm. However, certain events such as biological filtration of a marine aquarium, tend to reduce the carbonate hardness value and therefore lower the pH. Also certain influences, such as carbon dioxide, can affect the reading of pH value.
BIOLOGICAL FILTRATION
The assimilation of waste by bacteria in the filter of a marine aquarium is an acidifying process and in time will reduce the carbonate hardness value of the water. As this occurs, the pH value will fall. Carbonate hardness levels can be maintained with Aquasonic Carbonate Hardness Generator Powder. At a pH of 8.1 the carbonate hardness value should be 125ppm. If the carbonate hardness value of a marine aquarium is correct, yet pH values are not, the influence of carbon dioxide should be considered.
THE EFFECTS OF CO2
For pH to read correctly, carbon dioxide must be in equilibrium with the atmosphere. Carbon dioxide is produced by fish, plants, corals and bacteria assimilating waste in the biological filter in the aquarium. Some trickle (mini-reef) filters can expel carbon dioxide so effeciently that the quantity of carbon dioxide is less than the atmosphere, so pH reads higher than it really is. Likewise, in an aquarium with substrate filtration, carbon dioxide has some difficulty escaping as it is produced by the biological filter and other life. Under these conditions, carbonic acid may be formed and pH will read lower.
USING pH TO ADVANTAGE
During the development of bacteria in a biological filter, ammonia and nitrate conditions ensure. Both are deadly to marine fish. The toxicity of ammonia and nitrite, however, is in direct relation to the pH value of the water in the system. By lowering the pH, the toxicity of these deadly conditions is minimised. To lessen the toxicity of nitrite, lower the pH to 7.5.

Advice Care | For aquarium use only. Keep out of reach of children. Avoid contact with the eyes and skin. FIRST AID: If poisoning occurs, contact a doctor or Poisons Information Centre. If swallowed, do NOT induce vomiting. Give a glass of water and seek medical advice. If skin contact occurs, remove contaminated clothing and wash skin thoroughly. If in eyes, hold eyes open, flush with water for at least 15 minutes and seek medical advice. |

Feeding Guide | DIRECTIONS FOR USE: 1. Rinse a clean test tube several times in the water to be tested. 2. Fill the test tube to the 10mL mark. 3. Add 10 drops of Marine pH indicator and swirl. 4. Place the test tube on the white background of the colour chart with the light behind you. The colour in the test tube is best viewed with natural light. View immediately. The marine pH indicator has the advantage of an extensive colour change. Basically the colours may be interpreted: - Orange/yellow (at or below 7.5) is too low. - Purple (above 8.4) is too high. - Shades of red are the safe zone. - A pH of 8.1 is recommended. |
