Maintaining correct oxygen levels is an essential part of running a healthy fish tank. Fish, just like other living beings, need oxygen for respiration. Additionally, many plants in your aquarium will also need oxygen to facilitate photosynthesis.
If oxygen levels are too low, then this can result in stress and consequently the poor health of your fish.
That's why it is so vital to test the oxygen levels of your fish tank weekly and at Swell UK, we are proud to offer a range of trusted oxygen test kits from leading brand such as Tetra and Salifert at great value prices.
