## Summary description

Sera 04960 is a pack of Sera TEST QUICK 5-in-1 water test strips (model 20675) containing 50 strips. Each strip provides rapid semi-quantitative testing of five common aquarium water parameters for routine monitoring and maintenance. Designed for quick on-site checks to help assess water quality and support timely adjustments in freshwater and marine hobby use.

## Long description

The sera TEST QUICK 5-in-1 pack contains 50 test strips for fast, routine monitoring of key aquarium water parameters. Each strip gives a quick semi-quantitative indication of pH, carbonate hardness, total hardness, nitrate, nitrite and chlorine, enabling simple on-site checks to assess water quality and decide if further liquid testing or treatment is needed.
Advantages
The strips allow very rapid measurement with a one-second dip and a one-minute development time, producing easy-to-read color changes that are compared with the chart on the packaging. The procedure is safe, requires no reagents or equipment, and is suitable for hobbyists who need quick feedback on aquarium water conditions.
Suitable for
Routine monitoring of freshwater and marine aquaria
Quick checks after water changes or maintenance
Initial screening when fish show stress or unusual behavior
Hobbyists and beginners seeking simple, fast water parameter checks
When it may not be suitable
Test strips provide semi-quantitative results and cannot replace precise laboratory-grade or dedicated liquid tests when exact concentrations are required. For accurate measurement of small deviations or for diagnosing persistent water chemistry issues, follow-up with specific liquid tests is recommended.
Key specifications
Parameters tested: pH, carbonate hardness (KH), total hardness (GH), nitrate (NO3), nitrite (NO2) and chlorine (Cl2)
Quantity: 50 test strips per pack
Measurement method: colorimetric test strip with visual comparison to color chart
Reading time: 1 minute after immersion
How to use
Dip a single test strip into aquarium water for one second, remove it and wait one minute for the reagents to develop. Compare the colors on the strip to the chart provided on the packaging to read approximate values for each parameter. If results fall outside recommended ranges, use appropriate liquid tests or treatments to determine exact levels and take corrective action.
What to consider before purchase
Strips give semi-quantitative results — not as precise as liquid titration tests
Keep strips sealed and dry until use to maintain accuracy
Have reference charts and, if needed, liquid tests available for confirmation
Usage recommendations
Use the strips for regular quick checks—after water changes, when adding new fish, or if fish show signs of stress—and confirm any abnormal readings with dedicated liquid tests before making major adjustments.
