About Phosphates
There are two types, Organic and Inorganic. The type we test for in aquaria is the Inorganic type, PO4. All living matter contains phosphorus but unfortunately organic phosphate can only be tested for in laboratories using sophisticated testing equipment.
The Effect of Phosphates
In reef aquariums, levels of phosphates above 0.5ppm can adversely affect the growth of both hard and soft corals. It is recommended to keep phosphates at a maximum of 0.25ppm. In both fresh and saltwater aquariums phosphates above 0.5ppm can cause the growth of hair algae, blue green algae and other types of algae, including green water in ponds and lakes. A side effect of phosphate in saltwater aquariums is the precipitation of calcium.

FAQ
What type of phosphate does this test kit detect?
This test kit detects inorganic phosphate (PO4), which is the form commonly found in aquariums.
What is the recommended phosphate level for reef aquariums?
It is recommended to keep phosphate levels at a maximum of 0.25 ppm in reef aquariums.
Can this test kit detect organic phosphate?
No, this test kit only detects inorganic phosphate (PO4). Organic phosphate requires laboratory testing with specialized equipment.

The test results were accurate and easy to read. I noticed a drop in phosphate levels after using this kit regularly. It’s a reliable tool for maintaining healthy coral growth in my reef tank.

Simple to use and gives clear color changes. I use it weekly to monitor phosphate levels. It helps me catch algae issues early and adjust my water changes accordingly.
Una Blake –
Great value for the precision it offers. I’ve been using it for three months now and can consistently keep my phosphate levels below 0.25 ppm. My corals are thriving.
