COLOMBO - Phosphate Test - Analysis of PO4 Phosphates

The Benefits of Phosphate Nitrate Testing

Accuracy and Reliability The Colombo Phosphate Test provides accurate results, essential for nutrient management in the aquarium. Phosphates must be closely monitored as they directly influence the growth of aquatic plants and algae. This accurate test allows you to take proactive steps to balance your aquarium.

Ease of Use With clearly labeled components and step-by-step instructions, this test is extremely easy to use. Even beginner aquarists will find it simple to measure phosphate levels, ensuring proper aquarium maintenance without complications or confusion.

Algae Control Phosphates are a key factor in algae blooms. By monitoring and adjusting these levels regularly, you can effectively control algae growth, maintaining a cleaner, healthier aquarium for your fish and plants.

Plant Health Management Adequate phosphate levels are vital for the healthy growth of aquatic plants. This test helps you ensure your plants are receiving the necessary nutrients without encouraging the overgrowth of harmful algae, creating an optimal aquatic environment for all its inhabitants.

How to use the Phosphate Nitrate Test?

General instructions

• Always make sure the test tube is thoroughly clean before use.
• Clean it thoroughly after each use so that it no longer contains any chemical residue that could distort subsequent results.
• Take the water sample as carefully as possible.
• Hold the vial upright when counting drops.
• Make sure there are no air bubbles in the drops.

Test procedure:

1. Take a 10 ml water sample.
2. Add 5 drops of PO4-1 test liquid and shake the test tube.
3. Then add 5 drops of PO4-2 test liquid and shake the test tube.
4. Then add 2 spoonfuls of phosphate powder (tube with a blue cap) and shake the test tube.
5. Wait 10 minutes. 6. Determine the PO4 value of the water using the colorimetric card.

To judge the colour of the water sample after all the test liquids have been added, proceed as follows: Place the test tube on the colour card supplied with the kit and look simultaneously - from above - into the test tube and onto the card. Do not look under direct sunlight, but under indirect light. Compare the colour of the water sample with the colours on the card. The colour that matches best indicates the desired value. The colours of the sample and the card are not always identical, as the actual values are usually between two standardised values and therefore correspond to a mixture of two adjacent colours. In this case, it is necessary to judge approximately between which colours the sample actually lies.
