Salifert Oxygen Test Kit
The Salifert Oxygen Test Kit provides a quick and accurate way to measure oxygen levels in your saltwater aquarium. Oxygen is essential for the health of corals and marine fish, and maintaining saturation levels is critical for survival.
Due to the low solubility of oxygen in saltwater (approximately 5–7 ppm), it can be challenging to keep adequate levels, especially in systems using calcium reactors or CO2 injection, which may reduce oxygen concentrations.
This test kit includes 50 test strips for regular monitoring of oxygen levels in your aquarium water.

I’ve used this kit for several months now and it’s been very reliable. The test strips are easy to use and give clear results. My reef tank has been stable since I started monitoring oxygen levels regularly.
Michael Jones –
The kit works well for checking oxygen levels, especially after I added a calcium reactor. I noticed a drop in oxygen and adjusted my system accordingly. The strips are consistent and the instructions are clear.
