· If phosphate is present in too high a concentration there may be an increase in growth of undesirable algae and if the phosphate level is higher than 0.04 mg/L the growth rate of corals and calcareous algae may decrease by as much as 90%.

~Nitrate Profi-Test

· When there are insufficient areas of a tank which are deprived of oxygen (anaerobic zones) or denitrification is not taking place properly, nitrate will build up. This can also happen in an aquarium where the biological loading on the system is causing an imbalance e.g. if there is excessive livestock for the aquarium volume or over feeding is occurring.

~Salifert Magnesium Profi-Test

· Magnesium is present in natural sea water in a fairly high concentration (1350 - 1500 mg/L) and is an essential element of chlorophyll which is necessary for photosynthesis. Without photo synthesis plants, algae and coral would not be able to survive.

· Magnesium also helps to maintain the correct combination of calcium concentration and alkalinity as it slows down the formation of calcium carbonate which can absorb many important trace elements within the aquarium.

~Salifert KH/Alkalinity Profi-Test

· Calcium is not the only substance needed to form the skeletal material of corals and allow calcareous algae to grow. Carbonate and bicarbonate are also needed and these two substances can have a major effect on stabilizing or buffering pH levels in the aquarium in the correct range of 8.1 to 8.4.

~Salifert Calcium Profi-Test

· In a healthy aquarium, the growth and multiplication of corals, calcareous algae and other organisms can result in calcium depletion. To maintain a stable environment it is important that the calcium content should not fluctuate by more than 15 mg/L from the optimum range of 420 - 450 mg/L so regular testing should be carried out.

 

Salifert Potassium Reef Test Potassium concentration in natural seawater is approximately 400 ppm.

 

Iodine is present in natural sea water in a very low concentration (0.6 mg/L or 0.06 PPM) and this iodine occurs as several different species including iodide, iodate, molecular iodine and hypoiodite.

There is a misconception among many hobbyists that iodide predominates in natural sea water but in fact, it is iodate which is the predominant element.
