Phosphate - what is that?

Phosphate belongs together with nitrate to the macro nutrients.

Where does the phosphate in my aquarium come from?

Phosphates are usually introduced by food. However, dying organisms, contaminated water, sand or rocks can also lead to an increase in phosphate-levels. In addition, calcium reactors, which are operated with crushed coral, are a source of phosphate.

Why is the determination of phosphate important?

High phosphate concentrations can lead to unwanted algae growth. In addition, there are negative effects on the growth and coloration of corals. Therefore you have to ensure that the phosphate concentration in your reef aquarium is in a range of 0.01 - 0.05 mg/l.

Despite the negative aspects listed above, you should not forget that phosphate is a vital nutrient. A long lasting lack of phosphate will inevitably lead to the death of your corals.

Why Professional? Is a simple test not enough?

In seawater, phosphate is usually found in very low concentrations. In addition, the difference between a value of 0.02 mg/l and 0.07 mg/l phosphate is already enormous for most corals. To record these low levels correctly, a test with a very high accuracy is necessary. Furthermore the Tropic Marin Phosphate Test Professional contains a standard which allows you to check your measured values and correct them with a correction factor if necessary.
