This JBL kit connects the aquarium's gravel cleaner bell to the kitchen tap by means of 8 m of pipe: the flow of tap water creates the suction that empties the tank and cleans the substrate, then a lever reverses the direction to refill it. No more buckets to carry, for an aquarium 30 to 70 cm high.

The summary

What you receive: the gravel cleaner bell, 8 m of pipe, the tap pump and its adaptors.
How it siphons: the jet of tap water creates the suction that empties the aquarium.
Which aquarium it suits: a height of 30 to 70 cm, on the same floor as the sink.
Refilling: a lever on the pump reverses the flow and fills the tank.
The fitting: a 3/4 inch thread and M22, M24 and M28 adaptors.
Shipping: tracked parcel, delivered to your door.

Drain, clean the substrate and refill the aquarium from the tap, without carrying a bucket

A partial water change normally means filling buckets, carrying them to the sink, then making the trip again with clean water. The JBL ProClean Aqua In-Out kit does away with these back-and-forth trips. A gravel cleaner bell goes into the aquarium, an 8 m pipe connects it to a small pump screwed onto the tap, and the pressure of the tap water is enough to create the suction.

💧 How the suction works

When you open the tap, the jet of water passes through the pump and creates a vacuum in the pipe, which draws the water from the aquarium up to the sink, even if the sink is placed higher than the tank. Depending on the position of your sink relative to the aquarium, the flow either carries on by itself once the pipe is full, or you need to leave the tap running throughout the drain, at a rate of about two volumes of tap water for one volume of aquarium water. The kit thus compensates for a height difference of up to 1 metre, provided the sink and the aquarium are on the same floor.

The pump screws directly onto the tap spout, via a 3/4 inch thread, and the adaptors supplied cover the M22, M24 and M28 spouts with a 1 mm pitch, which fit most kitchen taps. Before ordering, unscrew the aerator from your tap to check that it does have a thread: a mixer tap with a pull-out spray head does not always have one, and the pump then cannot be fitted to it.

🪣 Emptying and cleaning the substrate

The gravel cleaner bell measures between 27 and 46 cm in length, which suits aquariums from 30 to 70 cm in height. Its rounded shape ends in a right angle: by rotating it through the substrate you create a vortex that lifts the dirt, and the angle reaches into the corners of the tank. As with the JBL ProClean Aqua-Ex gravel cleaner bells, a removable strainer stops plants, shrimps and small fish at the entrance of the bell, and two clips hold the hose in place on the edge of the aquarium or on the edge of the sink.

A magnet for the glass while the water level is low

A water change exposes the top of the glass, where algae cling most. A JBL Floaty II cleaning magnet cleans it from the outside while the level is low, without putting your hand in the tank. If its inner part comes loose, it floats and can be retrieved from the surface.

Take a 120-litre aquarium from which you change a quarter of the water each week. That means taking out 30 litres and putting back 30 litres, or six 10-litre buckets carried between the sink and the cabinet. With the kit, you stay by the aquarium: the gravel cleaner cleans the substrate while the water runs to the sink, then the tank refills through the same pipe, with no bucket to lift.

🚰 Filling through the same pipe

When the level has dropped enough, flip the pump lever: tap water flows back along the pipe and refills the aquarium by the same route. Beforehand, adjust the mixer tap so that the water arrives at the tank's temperature, and add your water conditioner as soon as filling begins if the mains water is chlorinated. This way the tank is refilled without a bucket, at a flow rate you control at the tap.

🌱 In aquaponics

In an aquaponic system, the fish water also feeds the plants, and the partial water change is used to remove the sludge that builds up at the bottom of the tank and to make up for evaporation. Because this kit does away with carrying buckets, this task becomes easier to keep up regularly. Do, however, measure the pH and hardness of your tap water before the first fill, as water very different from that of the system upsets the biofilter bacteria. In aquaponics, a pH of 6.4 to 7.5 and a KH of 6 to 12 °dH are the targets. The guide to regulating pH in aquaponics explains how to correct a deviation.
