For the serious pond keeper who leaves nothing to chance

A healthy pond with koi requires precision. Fluctuations in oxygen, ammonia, or phosphate can have serious consequences. The JBL ProAquaTest Lab Koi gives you the ability to test extensively and intervene quickly if necessary.

This test kit includes the following measurements:

• pH (3.0–10 and 7.4–9.0) – For precise acidity control in all types of ponds
• KH – Measures carbonate hardness and prevents dangerous pH fluctuations
• GH – Determines the amount of minerals in the water, important for fish and plants
• PO₄ Koi – Phosphate test for ponds with high fish populations (risk of algae blooms)
• PO₄ Sensitive – Detects phosphate levels in very low concentrations
• NH₄/NH₃ – Measures ammonium and determines the toxic ammonia content via a table
• NO₂ – Shows the presence of nitrite, harmful to fish in minimal amounts
• NO₃ – Provides insight into the nitrate content, important for algae problems and plant growth
• O₂ – Measures the oxygen content, essential for koi and biological processes
