These two bottles contain the reagents for the copper test, sufficient for approximately 50 measurements. They measure only the copper that remains dissolved in the water, the form that affects your livestock.

Outside of treatment, levels should stay below 0.05 mg/L, and readings are taken by comparing two samples in the comparator block. The test tubes, sampling syringe, comparator block, and colour chart from your kit remain in use.

The summary

Where to empty the test tubes: down the sink, then rinsed with clean water; the reagents never go into the fish water.
What the box contains: 2 bottles of reagents.
How many measurements: about 50, at 5 drops of each reagent.
When to use it: before introducing shrimp, and at the end of a treatment.
The waiting time: 15 minutes before reading, without exception.
Bottles only or full kit: the refill is enough if your comparator block and your two test tubes are in good condition.

The two reagents for the copper test, approximately 50 measurements, for aquarium and pond.

The 2 bottles in this refill extend your drop-based copper test for around 50 measurements, in an aquarium or a pond, using the test tubes, block and colour chart you already own. Without treatment, the level stays below 0.05 mg/L, read after 15 minutes. Test before introducing shrimp; these reagents, however, must never go into the water your fish live in.

Copper most often gets into a tank through tap water, when it has stood in copper pipework, and sometimes through an antiparasitic medication or an algae treatment that contains it. These two bottles are the reagents alone for the drop-based copper test, for around 50 measurements in freshwater, seawater and ponds.

The reaction only colours dissolved copper, the kind that affects your animals at the time of testing. Copper already deposited on the substrate as insoluble compounds is not included in the result, nor is copper that a water conditioner has bound: this complexed copper no longer poses a danger to the tank's occupants, and it is removed with water changes and filter cleaning. Your reading therefore shows the share that matters for your shrimp and fish.

🎨 15 minutes to develop

Fill two 5 ml test tubes, then add 5 drops of reagent 1 to one of them and mix, followed by 5 drops of reagent 2 and mix again. The colour takes 15 minutes to develop fully, and reading it any sooner underestimates the concentration. Both tubes are then placed in the comparator block, the blank tube compensating for the natural tint of your water, and the block is slid along the colour chart until the colours match.

Activated carbon to filter out dissolved copper

If your measurement reveals copper when no treatment has been used, place some activated carbon in your filter, which retains dissolved copper. Take another reading a few days later with the same set of vials, before introducing any invertebrates. The ammonium test usefully complements this check, since unexplained mortality can also come from nitrogen.

The first water from the tap carries concentrated copper

Let the stagnant water run out of the pipe before filling a bucket for the tank, because that is the water that picks up the most copper. For the same reason, do not use rainwater collected from copper gutters, and fit only copper-free metal parts in your tank or pond.

🦐 Invertebrates, fish and crops

Outside a targeted treatment, the copper content of a tank should stay below 0.05 mg/L, in freshwater as well as in seawater or in a pond. You therefore reach for these vials before introducing shrimp or snails, after an unexplained mortality, and at the end of a copper treatment to check that the water is free of it. In aquaponics, copper added to the fish tank then circulates into your growing beds, and the guide to limiting pests in aquaponics presents solutions that add none.

🧴 Storing the two bottles

Only reagent 2 is classified, with the signal word Warning and hazard statements H226 and H319: flammable liquid and serious eye irritation. Store both bottles tightly closed, in a dry place, at room temperature and in their original packaging, away from a lighting unit or any heat source. As the level must stay below 0.05 mg/L outside treatment, most of your measurements are read on the first field of the colour chart, and the set of 50 measurements covers several treatments and several introductions of invertebrates.

Unopened, both bottles keep for 3 years, which leaves time to space out measurements between treatments; an opened bottle deteriorates faster on contact with air. Keep the test tubes, the syringe, the block and the colour chart from your copper drop test, and order the refill before introducing shrimp or starting a treatment. The dosed water is poured down the sink: these reagents never go into the fish's water.

Technical specifications

What the refill contains

Contents: 2 reagent bottlesReagents 1 and 2, with child-resistant caps
Readings: Around 505 drops of each reagent per measurement, for the same volume as in the original case
Manufacturer's reference: JBL 2411500, PROAQUATEST rangeNot to be confused with 2411400, which is the complete kit
Matching test: Copper Cu testRef. 2411400, with its comparator block and its two-scale colour chart

Measuring copper

Recommended level: Less than 0.05 mg/LValid without treatment, in freshwater, seawater and in a pond
Waiting time: 15 minutesUntil the colour has fully developed. Reading too early underestimates the level

Hazard labelling

Signal word: WarningReagent 2 only, reagent 1 is not classified
Pictograms: Flame and exclamation mark
Hazard statements: H226, H319Flammable liquid and causes serious eye irritation
Precautionary statements: P101, P102, P305+P351+P338, P501
Precautions: Away from flame, out of reachBoth bottles screw down fully
Storage: 3 years, unopened bottlesOnce opened, they deteriorate faster when exposed to air

To allow for in addition

Glassware and syringe: Those of the copper testYou need two, one treated and the other in untreated water, which cancels out the water's own colour
Comparator block and colour chart: Those from the copper testThe colour chart carries a freshwater scale and a marine scale, which the block places side by side

The reagents alone, or the copper kit?

The chemistry and the number of tests are identical on both sides. What sets the two boxes apart is the comparison equipment, which carries over from one set of reagents to the next.

This test is read on two samples at once You need one treated test tube, one control test tube, and a block that holds them side by side in front of the right scale. Without these three parts in good condition, the two bottles alone are not enough.

When should you get this test out?

Why wait 15 minutes before reading?

Why is the marine scale separate?

How do you remove copper from water?

My reading is above the highest step, what should I do?

Dilute the sample with distilled water, repeat the test, then multiply the result by the corresponding factor.

Are these two bottles dangerous to store near the tank?

Only reagent 2 is classified, with the signal word Warning and the statements H226 and H319: flammable liquid and serious eye irritation.

The point that matters for storage is flammability: keep the box away from any source of heat or flame, and not on the cover of a lighting unit.

The caps are child-resistant and should be screwed back on fully. Take an empty bottle to the household recycling centre, to the collection point for household chemicals.

Empty the test tubes down the sink after reading: reagent 2 must never go into the fish water, nor into the shrimp tank.
