## Summary description

The sera 04310 water test kit is designed for measuring pH levels in water. It comes in a convenient hanging box and has a volume of 0.015 L. This kit is essential for maintaining water quality in aquariums and ponds, ensuring a healthy environment for aquatic life.

## Long description

The sera 04310 pH measurement kit provides a simple method to monitor pH levels in freshwater, marine water and garden ponds. Supplied in a small hanging box with 0.015 L of reagent, the kit is formulated to perform approximately 100 individual measurements and is intended for routine water-quality checks to support healthy aquatic conditions.
Advantages
The test kit is compact and easy to store or hang near aquariums and ponds. It yields quick, repeatable pH readings and includes enough reagent for around 100 tests, making it suitable for regular monitoring. The product is compatible with common corrective treatments: for low pH in freshwater use KH/pH-plus or for ponds use pond bio balance; for high pH in freshwater use pH/KH-minus or treat by filtering with super peat.
Suitable for
Routine pH monitoring in freshwater aquariums
pH checks in marine/aquarium saltwater environments
Regular testing of garden ponds
When it may not be suitable
This kit measures only pH and does not provide information about other important water parameters such as ammonia, nitrite, nitrate or carbonate hardness. For comprehensive water analysis, combine pH testing with appropriate kits for these additional parameters. The small reagent volume and compact packaging are intended for consumer and hobby use rather than high-throughput laboratory testing.
Key specifications
Intended use: pH measurement in freshwater, marine water and ponds
Reagent volume: 0.015 L
Approximate number of measurements: 100 tests
Packaging: hanging box for convenient storage
How to use
Collect a sample of aquarium or pond water in a clean test vial, add the specified number of reagent drops according to the included instructions, and compare the resulting colour against the kit’s pH chart to read the pH value. Rinse test glassware with dechlorinated water before and after use to avoid contamination. Record results and repeat tests regularly to track pH trends over time.
What to consider before purchase
Measures only pH — purchase additional test kits for ammonia, nitrite, nitrate or KH if needed
Sized for hobby use — check number of tests if you require very frequent measurements
Compatibility with corrective treatments you already use (freshwater vs. pond products)
Usage recommendations
Test at consistent times (for example weekly) and after maintenance or water changes; if pH readings fall outside desired ranges follow the product-specific corrective measures for freshwater or pond use to re-establish stable conditions.
