API PH Liquid Test Kit

Keeping an eye on pH is one of the simplest ways to look after a freshwater tank. This liquid test kit from API gives you a quick, dependable reading of how acidic or alkaline your aquarium water is.

pH sits at the heart of water chemistry and has a direct bearing on fish health, plant growth and the balance of the tank. It can shift over time as fish waste builds up, food breaks down or additives are used, so testing at regular intervals keeps the level within a healthy range for your aquatic life.

Why It's Important

• Monitors pH levels: shows whether your water is acidic or alkaline, so you can confirm conditions are steady and safe for fish and plants.
• Supports fish health: a pH that drifts outside a fish's preferred range can cause stress or illness, and testing lets you spot and correct that early.
• For freshwater aquariums: suits community tanks, tropical setups and everyday freshwater use.

Easy to Use

Inside you will find a liquid indicator solution, a test tube and a colour comparison chart. Fill the tube with tank water, add the stated number of drops, then hold the resulting colour against the chart to read the pH.

Range and Accuracy

The kit reads pH accurately across the range normally seen in freshwater aquariums, which helps you hold conditions at their best for fish and plants.

Great for Routine Care

Adding a regular pH check to your maintenance routine means you can be sure water chemistry stays balanced, and it gives you a clear basis for decisions on water changes and treatments.
