Aquarium tests are essential tools for checking water values and maintaining the chemical balance necessary for the well-being of fish, corals, and plants.

Regularly monitoring parameters such as pH, KH, GH, ammonia (NH₃/NH₄⁺), nitrites (NO₂⁻), nitrates (NO₃⁻), phosphates (PO₄³⁻), calcium (Ca), and magnesium (Mg) is crucial to prevent imbalances that can compromise the health of the aquarium.

Our selection includes liquid reagent tests for maximum precision, test strips for quick measurements, complete kits for multi-parameter control, and digital instruments such as pH meters and conductivity meters.

With regular testing, you can correct any imbalances in time and ensure a healthy and stable environment for fish, invertebrates, and aquatic plants.

Tip: Perform tests consistently, especially during the start-up phase or when introducing new organisms; preventing is always easier than correcting existing imbalances.
