Tetra Oxygen Test Kit

Tetra Oxygen Test Kits are available from Swell UK at discount prices.

Oxygen is vital for all organisms living in your aquarium or pond. fish, plants, and microorganisms all require oxygen for respiration. Low oxygen concentrations can cause fish to be increasingly susceptible to disease and cause biological filtration bacteria to work inefficiently.

The oxygen concentration in the water of your aquarium or pond is dependent on a number of factors including; temperature (oxygen concentration decreases as temperature increases especially above 80°F), overstocking, heavy amounts of decaying organic matter, and poor circulation or surface films that interfere with natural gas exchange. Additionally, live plants which use carbon dioxide for photosynthesis during light hours change over to oxygen respiration at night and actually add to oxygen demand.

The Tetra O2 Test Kit was professionally developed to accurately determine the oxygen level of your aquarium water.
The kit contains enough material for 30 tests, including:-

Two 9-ml test reagents (#1 and #2),
• One 10-ml test reagent, a test vial, color scale, instructions and recommendations.

This kit is suitable for Freshwater (including outdoor ponds), Brackish and Saltwater systems.
Test the water in your aquarium weekly to ensure optimum water quality.
