Everyone knows the importance of checking a tank’s Alkalinity, Calcium and Magnesium but what about Phosphorus? There is some debate about the right amount of Phosphorus to have in a reef tank, since too much can cause algae issues or impair coral growth but too little may also have detrimental impacts on corals. Regardless of what side of the debate a reefer is on, knowing the Phosphorus levels in a reef tank can help to avoid algae issues before they get out of control, or, conversely, identify if levels are possibly too low.
While there are many ways to check Phosphorus levels in a home aquarium, by far the easiest and quickest method is the Hanna Phosphorus Ultra Low Range Checker. The ULR checker will measure Phosphate between 0.0 and 0.90 ppm. This is ideal for the vast majority of reef hobbyists who require a precise level of phosphate control. An easy to read chart is included to help convert the parts per billion (ppb) readout provided by the checker to the more commonly used parts per million (ppm).
In order to use the Hanna Phosphorus ULR Checker a sample of tank water is mixed with the testing reagent and placed in the checker. A simple click of a button provides almost instantaneous results, without the need to interpret a colour chart. This prevents human error and provides the most accurate results possible.
Phosphorus is one of the most under tested reef tank parameters but keeping it at levels that are not too high or too low can help to improve coral health and growth.
