What level should you aim for?

Aim for phosphate as close to zero as possible. Plants only need trace amounts, between 0 and 0.25mg/L (PO4-P). Higher levels feed algae. In time, they can also upset the mineral balance in your fish.

If your level is too high

Regular partial water changes are the first step. Use dechlorinated tap water. Also, test your tap water for phosphate. Otherwise, you may add more with every water change. If levels stay high, a phosphate-binding treatment or filter media can help.

FAQs

How long does the test take? 5 minutes. Then you compare the colour to the chart.

What is a good phosphate level? As close to zero as possible. Trace amounts of 0 to 0.25mg/L (PO4-P) suit plants.

Why does phosphate cause algae? Algae feeds on phosphate. The more there is in the water, the faster algae grows.

Can my tap water contain phosphate? Yes. Test a fresh tap water sample to check.

Is this kit for freshwater tanks? Yes. This is the freshwater aquarium phosphate test.
