Oxygen is among the most essential gases that are required for survival. Whether it is humans, birds, small animals, dogs, cats, or fish; no one can survive without the necessary amounts of oxygen. When you are setting up a fish tank, it is recommended to test the water for all types of essential and unwanted additives. And one such important aquarium water test is the oxygen test.
Usually, oxygen levels are affected by change in temperature, the number of fish in the tank, circulation of water, and tension of the surface film. The Tetra Oxygen Test Kit provides you with accurate readings of the oxygen levels in your aquarium water. Using this dissolved oxygen test kit is important so that your fish can thrive without any troubles. As soon as you use this test on your fish tank’s water, it will let you know whether it is time to take some measures to provide a better environment for your fish.
A decrease in oxygen levels can cause stress to fish and leave them susceptible to harmful diseases and eventually, death. This can also disrupt the working of the biological filtration equipment you are using. So, you must use this aquarium O2 test kit regularly to keep the oxygen levels maintained. The Tetra O2 test kit comes with two 9ml test reagents, a test vial, instructions and a colour scale, all of which are ideal to carry out up to 30 oxygen level tests. Also, you can use this test for both saltwater and marine aquariums, irrespective of the type of fish you have.
