PO4 ProAqua Phosphate Test for Koi

JBL PO4 ProAqua Phosphate Test Koi

A healthy pond with near-natural conditions
The correct water parameters in the pond depend on the fish stock and the plants present. Even if the water looks clear, it may still be contaminated. Poor water parameters can lead to diseases or algae growth in the pond. For a healthy pond with near-natural conditions, regular monitoring and adjustment of water parameters are essential.

For every water analysis, JBL offers water tests in the form of rapid tests or color-change tests. These determine a specific value or multiple values simultaneously. With these water tests, algae problems can be detected and negative nitrate, nitrite, potassium, magnesium levels, etc., can be identified.

Why test:
Phosphate is an important plant nutrient. In natural bodies of water without pollution, the phosphate concentration is around 0.01 mg/l. Plants and algae have adapted to this limited supply of phosphate and can therefore thrive on very small amounts.
In koi ponds, phosphate enters the water mainly through the fish’s digestive processes and via uneaten food. Especially with high fish stocking densities, phosphate levels can reach values that are sometimes 100 times higher than natural levels. Phosphate input from pollen in the spring or from garden
fertilizers in the surrounding area should also not be overlooked. Some water treatment plants also add phosphates to tap water to prevent lime deposits and corrosion in the piping system. As a result of this unnaturally high nutrient supply, algae multiply at an explosive rate.

Procedure:

1. Rinse both test tubes several times with the water to be tested.
2. Using the included syringe, fill both test tubes with 5 ml of sample water each.
3. Add 1 large measuring spoon (wide end of the included double spoon) of Reagent 1 to one of the test tubes, close with the lid, and shake until the powder has dissolved. Add 5 drops of Reagent 2, mix by swirling, and let stand for 10 minutes until the color has fully developed.
4. Place both test tubes in the gray comparator block: the tube with the added reagent at the smooth end of the comparator block, the tube with untreated sample water (blank sample) at the notched end.
5. Place the comparator block with the two test tubes on the color chart so that the notch faces the values, and slide it along the color chart until the color of the sample with added reagent matches the color below the blank sample as closely as possible.
6. Read the phosphate content in the notch of the comparator.

Correction of deviating values:
Too low: Not applicable.
Too high: Reduce using JBL Phosphate Remover. As a preventive measure, feeding according to the fish’s needs and species, e.g., with food from the JBL ProPond series, is helpful

Use biocides with caution. Always read the label and product information before use.
