Colombo PO₄ (Phosphate) Test Kit

Colombo PO₄ (Phosphate) Test Kit — Accurate Pond Water Phosphate Testing

Control algae growth and protect water quality with the Colombo PO₄ Phosphate Test Kit — a professional drop-test kit designed for precise phosphate (PO₄) measurement in ponds and aquariums.

Key Features & Benefits:

• Professional-grade accuracy — measures phosphate levels with precision, helping pond keepers detect nutrient imbalances early.

• Essential for clear water — excess phosphate is one of the main causes of algae blooms, green water, and blanketweed problems.

• Simple & reliable — comes with easy-to-follow visual instructions and a color reference chart for quick result interpretation.

• Complete kit — includes test tubes and reagents, with capacity for up to 40 phosphate tests.

• Fast results — get accurate readings in minutes, so you can take corrective action (water changes, phosphate removers, or filters).

• Trusted by koi keepers & pond hobbyists to maintain balanced nutrient levels and protect fish health.

Why Test for Phosphate?
Phosphates (PO₄) naturally accumulate from fish waste, uneaten food, and decaying plants. Left unchecked, they can:

• Fuel uncontrolled algae growth

• Reduce oxygen levels in water

• Lead to poor pond clarity and stressed fish

By regularly using a Colombo phosphate test kit, you’ll ensure your pond’s ecosystem stays in balance — keeping water clear, healthy, and algae under control.

How to Use:

1. Collect a pond water sample in the provided test tube.

2. Add the recommended number of reagent drops.

3. Compare the color change with the included chart.

4. Record and monitor phosphate levels regularly.
