Phosphate is an essential component in fish nutrition but is also produced as a waste product by fish. Phosphate is practically non-toxic to fish, but excess phosphate can cause unwanted algae and will inhibit coral growth.

Maintaining a low level of phosphate is essential for reducing unwanted algae and maintaining coral growth rates. Phosphate tends to accumulate as an aquarium matures, so regular monitoring of phosphate is required to determine the health of the aquarium.

Phosphate in natural seawater generally varies from 0.01 mg/l to 0.06 mg/l (in terms of phosphorus) in reef areas. However, in a reef aquarium, aim for 0.03 mg/l to maintain good coral growth and keep nuisance algae at to a minimum.

Regular maintenance and use of partial water changes with a good quality reef salt should help to keep phosphate low. To remove additional phosphate, use of Phosphate Remover in your filter or add Anti-Phos liquid regularly to instantly remove phosphate.

NT Labs Marine Lab Phosphate Test Kit will help you understand the importance of water quality. By having the correct parameters and good water quality, it will help your fish, invertebrates and corals live longer, healthier lives.

Highly accurate, the NT Labs Marine Lab Phosphate Test Kit contains liquid reagents which work by changing the colour of a water sample in relation to the concentration of a given substance. Simply compare the colour of the sample to the easy-to-read colour charts or count the number of drops it takes to alter the colour of the sample.

The tests are liquid drop tests from a calibrated dropper bottle, so all the drops are the same size. Just add your aquarium water to the test tube and count the drops needed. The back of the box details clear pictorial instructions so you can see what to do from the start. A set of colour coded stickers is provided to label both the test tubes and test tube lids, so you always conduct the same test in the same test tube avoiding contamination. Full instructions are included detailing optimum levels and suggestions for correction.

Suitable for marine, reef and brackish aquariums.
