Sera Test PO4

  • Sera Phosphate Test Kit (60 Tests) makes it easy to regularly monitor the phosphate (PO4) level in freshwater and saltwater aquariums as well as ponds.

Phosphate strongly promotes algae growth. Thus, it should be regularly checked. The phosphate level should be below 1mg/L (ppm) in freshwater and 0.1 mg/L (ppm) in saltwater.

Both fish waste and feeding are possible causes for phosphate introduction into the water. A part is taken up as a nutrient by plants, an excess, however, provides nutrition for unwanted algae. The sera PO4-Test quickly and easily provides an overview of current phosphate levels. Excess phosphate is easy to remove with sera phosvec (freshwater) or sera phosvec Granulat (fresh and marine water) or sera pond phosvec (pond).

  • Glass Vial - 20ml
  • Measurement Spoon
