NT Labs Phosphate Test

What is Phosphate?
Phosphate is a major nutrient found principally in fish food to help with growth, good bone formation and many other biological processes. However, not all of the phosphate will be utilised by the fish and will be excreted as a waste product. It can also be generated by the breakdown of other organic matter and is also often present in tap water. While phosphate is beneficial for life, it is only required in small quantities.

Why test for Phosphate?
Increased phosphate in the water column is often a major contributor to the growth of nuisance algae.  At low levels, it is generally considered safe for fish, but should be monitored for algae prevention.  Higher concentrations of phosphate can start to interfere with the mineral balance within fish.

What is the correct phosphate level?
The ideal phosphate concentration should be as close to zero as possible. While some phosphate is desirable to aid with the healthy growth of higher plants, only trace amounts between 0 and 0.25 mg/L PO4-P are required.
