Marine Aquarium Water Testing & Analysis
Professional In-Store Water Testing at Rock ’N’ Critters
Concerned about your aquarium water quality, experiencing problems with your corals or simply want reassurance that everything is running smoothly?
Our Marine Aquarium Water Testing & Analysis Service provides accurate water chemistry testing alongside practical advice from our experienced marine aquarium team.
Bring a sample of your aquarium water to Rock ’N’ Critters in Barry, and we'll help you understand what's happening inside your aquarium.
What's Included?
Our standard £20 water analysis covers four important marine aquarium parameters:
-
Salinity – Checks salt concentration and helps maintain stable marine conditions.
-
Nitrate (NO₃) – Monitors nutrient levels that can affect coral health and algae growth.
-
Phosphate (PO₄) – Helps identify nutrient imbalances and potential algae problems.
-
Alkalinity (KH) – Measures buffering capacity, important for pH stability and coral growth.
Additional Testing Available
For customers requiring further analysis, we also offer:
-
Calcium (Ca) – Important for stony corals and coralline algae.
-
Magnesium (Mg) – Supports calcium and alkalinity balance.
-
Copper (Cu) – Useful for investigating contamination or monitoring copper treatments.
Additional tests may incur extra charges.
More Than Just Test Results
We don't simply provide numbers. Our team can explain your readings and offer practical guidance on:
-
Investigating coral or fish health concerns

Managing nitrate and phosphate
