The summary

  • What you receive: a graduated translucent plastic measuring jug, in the capacity of your choice, from 500 ml to 5 L.
  • Which capacity: 500 ml or 1 L for diluting a product, 2 L or 5 L for measuring water.
  • Its uses: monitoring evaporation, measuring out a fertiliser or a pH corrector, checking the flow rate of the pump.
  • Cleaning: a rinse with clean water between products, by hand.

Translucent measuring jug with spout and handle, from 500 ml to 5 L

This graduated measuring jug in translucent plastic measures water and nutrient solutions precisely, with no need for scales. Its pouring spout guides the flow, and its handle is moulded as one piece with the body so you can hold it full with one hand. Read the graduation with the jug sitting flat on a surface, at eye level, in 500 ml, 1 L, 2 L or 5 L.

📏 Four sizes, four uses

500 ml

Graduated every 50 ml, the smallest format is ideal for diluting a pH corrector or a fertiliser for a small tank.

1 L

The 1 L bottle retains the 50 ml graduation line and is used to prepare the dilution for a large reservoir.

2 L

The 2 L jug, graduated every 100 ml, measures top-up water for a pot, a small tower unit, or an aquarium.

5 L

The 5 L version adds a half-litre scale and fills a large reservoir in fewer pours.

🐟 Its uses in aquaponics

In an aquaponic system, the measuring jug is not just for pouring water: it allows you to measure what enters the circuit and what leaves it. All of these steps rest on the same principle, as fish tolerate sudden changes in water quality poorly: by knowing your volumes, you make corrections in small increments rather than dosing by guesswork.

Evaporation

A mark set at the full level of the tank and the top-up water counted in glasses give you the volume lost each week.

Fertilisers and pH correctors

The product is diluted in a measured volume of water, then poured slowly into the tank where circulation is greatest.

Water change

The 5 L jug measures the replacement water, and therefore the corresponding dose of water conditioner, litre by litre.

Pump flow rate

Time how long it takes to fill a 5 L jug at the pipe outlet: if it fills in 10 seconds, the pump is delivering 1,800 L/h.

Check the pH in the glass before pouring

A solution prepared in the jug can be checked before it joins your reservoir. Draw off a few millilitres: the drop-based pH test for nutrient water gives you the value by colour. You can then correct a few litres rather than the entire circuit, using a corrector dosed more precisely.

Each concentrate is poured into the water

Never mix two concentrates directly together in the same container, for example a fertiliser and a pH corrector. Fill the container with water first, add one product, stir, then add the next. Keep that container for garden use only afterwards.

💧 Monitor evaporation every week

Through evaporation and plant transpiration, the level in a tank drops faster the warmer it gets. Stick a piece of tape at the full mark, then once a week top up with water to that line, counting how many jugs you pour in. The volume you note down tells you the actual consumption of your system, and a sudden increase with no heatwave is most often a sign of a leak or an overflow. Pour this top-up water slowly, either rested or pre-treated, so that its temperature and chlorine content do not cause a shock to your fish.

🧪 Measuring out a fertiliser or a corrector

To prepare a nutrient solution, fill the measuring jug with water up to the desired mark, then add the dose indicated on the label of your hydroponic fertiliser, multiplied by the number of litres. At 2 ml per litre, a 5 L jug therefore receives 10 ml, a small dose best measured with a graduated syringe or a dosing cap. In aquaponics, the same method applies to supplements that the fish do not provide in sufficient quantities, such as iron, and to pH correctors. To adjust the pH, dilute the product in a glass of water taken from the tank, then pour it in slowly, in several stages if necessary, so that the value changes gradually.
