Determination of the optimum phosphate value for ideal plant growth or of possible cause of algae in freshwater and marine water.
Laboratory comparator system to compensate the inherent water colouring: fill glass vials with sample, add reagents to another vial, place vials in holder, read values on cloud chart.
To use: when setting up a new freshwater aquarium, once a week. With algae problems and for checking tap water.
Online laboratory: free analysis and recommendations for the water values you have measured.
Package contents: 1 quick test, Phosphate test PO4. Contents for approx. 50 measurements. Incl. 2 reagents, 2 glass vials, with screw cap, syringe. dosing spoon, comparator block and colour scale. Refill reagents available separately.
In a aquarium, phosphate primarily enters the water as a result of the digestive processes of the fish or in the form of food remains. In ponds, phosphate primarily enters the water as result of leaves and dying pond plants/algae. If condition are unfavourable, the phosphate levels may reach values that are sometimes 100 times higher, and more, than natural levels.
Recommended phosphate values:
Freshwater aquarium (community aquarium): 0-0.4 mg/l
Lake Malawi/Lake Tanganyika aquarium: 0-0.4 mg/l
Plant aquarium with few fish (aquascaping): 0.1-1.5 mg/l
Marine aquarium: 0-0.1 mg/l
Pond: <0.05 mg/l
