Frequently Asked Questions

Do I need to test my aquarium water?

It's vital to test your water if you are keeping any livestock to make sure that conditions are safe for fish and invertebrates. Dangerous and toxic conditions cannot be seen or smelled, so regular testing is essential.

When should I use an aquarium water test kit?

Before the nitrogen cycle has established, you should test daily or every few days for around 4-6 weeks after setting up a new fish tank, until nitrate is present and ammonia and nitrite are 0. Once your tank is table and established, you can drop testing to once or twice a month, but be sure to test before adding new fish or if any fish get sick.

How do I test fish tank water?

Test your aquarium water using a digital freshwater test kit, and following the provided instructions. Regular tests of ammonia, nitrite, nitrate, and pH help you to maintain and monitor your water quality, keeping the environment healthy for aquatic life.

Why choose a digital tester?

Unlike test strips, digital water testers provide an easy to read display that eliminates the need for colour matching, reducing the chance of errors. Although the upfront cost is higher, these test kits only need replacement reagents, making them a better long-term solution and allowing for more regular testing.
