**** – Essential Aquarium Water pH Testing Kit
The API pH Liquid Test Kit is a simple, accurate and reliable solution for monitoring the acidity (pH level) of freshwater aquarium water. pH is a key measurement of water chemistry that affects fish health, plant growth and overall tank balance — and it can change over time due to fish waste, food decay or water additives. Regular testing helps you keep your tank’s pH within a healthy range for your aquatic life.
Why It’s Important:
🌡️ Monitors pH levels: Measures how acidic or alkaline your aquarium water is so you can ensure conditions are stable and safe for fish and plants.
🐠 Supports fish health: Fish can become stressed or ill if the pH drifts too far from their preferred range — testing lets you catch and correct changes early.
💧 For freshwater aquariums: Ideal for community tanks, tropical fish setups and general freshwater use.
Easy to Use:
The kit includes a liquid indicator solution, a test tube and a colour comparison chart. To test, fill the tube with aquarium water, add the recommended number of drops of test solution, then match the resulting colour against the chart to read your pH level.
Range & Accuracy:
Designed to accurately measure pH in the typical freshwater aquarium range, helping you keep conditions optimal for your fish and plants.
Great for Routine Care:
Incorporating regular pH testing into your aquarium maintenance routine gives you confidence that water chemistry stays balanced — and helps you make informed decisions about water changes and treatment.
