This Salifert Oxygen Profi Test Kit is ideal to test the amount of oxygen in a reef or marine aquarium.
Corals, fish and other marine life needs a very high level of oxygen, due to the low solubility in natural sea water. To maintain healthy growth and development it's important to routinely test levels and act accordingly.
This test works incredibly quickly, giving a reliable reading in just a few minutes, on a scale from 2 - 14mg/l.
The kit contains 40 tests, so not only is a top quality product, it's great value for money too! Order before 3pm to receive your order the next working day, and if the order is over £50, then delivery is free!
