Help and advice on shopping for: Aquarium Test Kits

Get a better view of your aquarium water

Keeping an eye on the chemistry of your fish tank water can be much more difficult than it seems at first. At Swell UK we stock a wide range of aquarium water test kits from top brands like Red Sea, Seneye and Tetra to help you identify the chemical makeup of your water, fix it and protect your marine life.

What are aquarium test kits?

Aquarium water test kits are various chemical tests that are easy to perform on your aquarium. They range from test strips, that you simply dip into the water, to colour changing compounds, that react to the presence of a certain chemical in a sample from your aquarium. These tests allow you to quickly diagnose any issues within your water so you can fix them with an appropriate water treatment.

Why should I buy water test kits?

You must maintain the correct water chemistry to avoid stressing your fish or damaging your aquarium hardware. As it’s impossible to see a chemical imbalance before it causes serious damage, the only way to keep an eye on your aquarium is with a set of water test kits.

What are the main types of aquarium test kits?

We sell a wide range of test kits to monitor every aspect of your aquarium water chemistry. Ammonia, calcium, copper, nitrate, nitrite, oxygen, pH, phosphate and salinity testers all test for the presence of one particular chemical within your water. Master test kits contain a variety of tests to check multiple aspects of your water chemistry. Quick test kits are designed to be used regularly and test for any immediate issues within your aquarium. Finally, specialist test kits are used to monitor other chemicals that are less likely to have a bearing on the overall water chemistry but are important to specific aquarium setups.

What should I look for?

Ensure that the test kit you’re buying is suitable for your type of aquarium, as the water quality required for a marine tank is very different to that needed for a cold water tank. Beyond that, it’s really about ensuring you’ll have enough test kits to perform regular tests, if in doubt we recommend stocking up so you don’t run out in a pinch.
