JBL PROAQUATEST COMBISET Plus NH4

JBL PROAQUATEST COMBISET Plus NH₄ – Core Water Parameters Kit for Freshwater Aquariums

Stay on top of your tank’s chemistry with the JBL PROAQUATEST COMBISET Plus NH₄. Packed in a durable, waterproof case, this kit covers the essential freshwater parameters and adds a dedicated ammonium/ammonia (NH₄/NH₃) check perfect for cycling tanks, community setups and planted aquariums.

Which parameters are covered?

• pH (3.0-10) – overall acidity/alkalinity
• KH – carbonate hardness for pH stability
• NO₂ – nitrite (toxic at very low levels)
• NO₃ – nitrate (algae driver / plant nutrient)
• NH₄/NH₃ – indicates safe ammonium and lets you determine toxic ammonia via the included table

Includes a CO₂ calculation table based on your measured pH & KH.

Key features

• Comparator system compensates natural water tint for more reliable color reads.
• Child-safe reagent bottles in a waterproof case for storage and travel.
• Fast, simple procedure with clear color charts and drop-count method for KH.
• Refillable, most reagents available separately to reduce waste and cost.

Designed for freshwater aquariums (tropical, community, planted).

What’s included

• 9 reagents
• 3 glass vials with caps + 1 plastic vial
• Syringe & measuring spoon
• Comparator block
• Color charts & analysis/record sheets
• Instructions (quick to follow)

Everything organised in a robust, waterproof carry case.

How to use (quick guide)

1. Use the syringe to fill the vial to the mark with aquarium water.
2. Add the specified drops/powder for the chosen test.
3. Insert vials into the comparator and wait the indicated time.
4. Match the color to the chart (count drops to endpoint for KH).
5. Log results; use the pH+KH table to read your CO₂ and the NH₄ table to infer NH₃.

Pro tips

• Cycling & after changes: Test more frequently during the first weeks and after filter/media changes.
• Out of range? If a value exceeds the scale, repeat the test with distilled-water dilution to bring it into range (see instructions).
• Trend tracking: Keep your record sheets; trends matter more than single readings.

FAQs

Is it suitable for marine or ponds?
This set is tailored for freshwater aquariums. For marine/pond testing, see JBL’s dedicated kits.

How often should I test?
Weekly for stable tanks; 2-3×/week during cycling or when troubleshooting livestock stress/algae.

Can I buy refills?
Yes, most reagents are available individually so you can top up as needed.
