D&D test kits are designed to test your aquarium water for harmful chemicals which can cause problems for your tank inhabitants.
Harmful chemicals don't necessarily mean the end of your tank, problems can be solved with appropriate treatments and additives which can help to remove the negative elements from the water.
They also are beneficial for ensuring that certain beneficial elements are present, such as iodine, which is considered a necessity for certain biological processes in many marine animals. While fish can gain their iodine from food, corals and other invertebrates take up iodine directly from the surrounding water.
D&D are a highly respected company within the aquatics industry, and Swell UK are pleased to sell their test kits at our famously low prices.
