TetraPond Kits are both reliable and accurate, using professionally designed methods to determine if your water is safe for Koi Fish.

Oxygen is vital to the well-being and overall condition of fish, plants and filter bacteria. Water contains far less oxygen than air, and at times it can become limiting. It is important to check oxygen levels from time to time, particularly at warmer times of the year. The only way to check the oxygen level is with a TetraTest Oxygen test kit.
