Aquarium test kits and water testing

Water testing helps separate a measured aquarium problem from a guess. Routine home tests provide timely checks of parameters such as alkalinity, calcium and nutrients, while laboratory analysis can investigate a broader selection of elements and contaminants.

Choose the test for the question you need answered and follow its sampling or reagent instructions precisely. Record results alongside dosing and water changes so trends are easier to interpret. A laboratory result is a snapshot of the sample submitted; use it together with regular observations and repeat measurements when deciding on adjustments.
