Aquarium Water Test Kits

Water test kits for Tropical aquariums, Coldwater aquariums and Saltwater marine aquariums. All to help ensure the correct conditions and reducing the need for fish medicines.

Regular water testing will help all aquariums achieve and realise the health and beauty they are capable of demonstrating when all essential conditions are met. Fish that are exposed to even small consistent levels of nitrite that may be the result of an improperly maintained or sized filter system may perish or never seem as vibrant as they can be. Corals that are deprived of the KH values they require for growth and sustenance may also perish or never demonstrate their true beauty. Plants that are constantly lacking essential trace minerals such as iron may perish or never demonstrate the rich vibrant greens and reds that make a planted aquarium a unique underwater garden.

Evolution Aqua Pure Aquarium is a new and unique aquarium treatment for maintaining crystal clear and healthy aquarium water.

In order to maintain and create optimal water conditions for fish, plants and invertebrates water testing is essential. It is not possible to simply look at an aquarium and be aware of conditions that may need to be adjusted or toxins that are accumulating to lethal levels. It is impossible to understate the benefits of regularly testing aquarium water. Active thriving colourful fish, plants and corals are just a test away; not testing on the other hand can be the cause of being unaware of what can easily be prevented.
