Product information

Regular water changes
Food, plant remains and metabolic products pollute the aquarium water. Since aquarium filters can’t completely remove these substances from the water and a large part of the waste enters the aquarium bottom, a regular partial water change (about every 2 weeks 1/3 of the water content) needs to be carried out. Always siphon off the waste from the substrate when carrying out a partial water change. After the partial water change a good water conditioner such as JBL Biotopol is vital to render the new tap water suitable for fish.

Easy to install
Connect the water jet pump to the water tap. Connect the long hose to the water jet pump and the other end to the gravel cleaner. Hang the gravel cleaner inside the aquarium. Set the stopcock on the water jet pump to flow. Completely turn on the tap. The aquarium water will be sucked in by the water flowing past. While the water is being sucked in, clean the bottom of the aquarium with the gravel cleaner. To refill the aquarium, close the stopcock on the water jet pump and let fresh water flow into the aquarium.

If the 8 m hose is not enough, there is an extension set (JBL PROCLEAN AQUA IN-OUT Extension Set).

How to clean the aquarium bottom properly:
Push the gravel cleaner into the aquarium substrate with a twisting movement. The suction will pull the substrate and the dirt upwards into the gravel cleaner. The substrate will then fall back down under its own weight and only the dirt will be sucked out of the aquarium. With fine sand, you can adjust the suction by lifting the gravel cleaner so that the light sand also falls back down.
If you have a long-term substrate fertiliser underneath the covering gravel layer (e.g. JBL PROFLORA AQUA BASIS), do not insert the gravel cleaner far. Insert it only as deeply as the covering substrate layer is thick.

JBL Aqua In-Out: The adapters that come with it don't fit on the faucet in the kitchen or the one in the bathroom. Neither do they fit on the bathtub faucet. Where can I get the right adapters?

Unfortunately, I can't provide information on where you can find a suitable adapter in your area. All I can recommend is trying a conventional bathroom fittings shop.

JBL Aqua In-Out stopcock: Sometimes there is no suction at the drain. What might be the cause?

It is impossible to determine why there is too little suction in a specific case by remote diagnosis. Factors such as the water pressure of the water mains, length of hose and whether there are any clogs in the system my be involved.

The suction is needed

a) when the Aqua In-Out is started up
b) permanently when the drain is higher than the water level in the tank.

Why does the hose always pop off at the coupling?

Have you made sure that the hose was positioned securely in the guide (between the connector and the "flexible knobs") at the coupling when the hose was installed? This is important because pressure is exerted on the hose when the coupling piece is screwed fast so that it can no longer come off.



Simple & clever aquarium cleaning: JBL PROCLEAN AQUA IN-OUT & AQUA EX

The AQUA IN-OUT aquarium cleaning system is one of the most popular JBL products! No wonder, because siphoning aquarium water with a substrate cleaner (gravel cleaner) and refilling it directly with the same system from the tap with just one turn of the lever is so easy and convenient that you simply can't say no to it.

Non pensavo che un semplice sifone potesse essere così di alta qualità! Materiali premium, comoda griglia alla fine del tubo che evita di aspirare pesci, gamberi o detriti troppo grossi. Semplifica e di molto la manutenzione! inclusa anche una comoda clip per fissare il tubo al secchio, o al lavandino in caso di carico e scarico diretto!

Ein super Produckt

Klare Kaufempfehlung

Wenn man keine lust hat zig Eimer hin und her zu schleppen ist das auf jeden Fall ein sehr sinniger Helfer.

D. Rost - German

Hier handelt es sich um ein Produkt das ich beim Wasserwechsel nie mehr missen möchte! Endlich kein Eimerschleppen mehr!

Die Wasserstrahlpumpe sorgt für ein angenehmes Leeren und Füllen des Aquariums.

Mit Hilfe der Klammer und der eckigen Form der Glocke bleibt die Glocke von alleine im Aquarium, ohne das man sie mit den Händen fixieren muss. Damit hat man in der Zwischenzeit beide Hände für andere Arbeiten zur Verfügung :)

ProTipp: Einfach einen Nylonstrumpf über die Glocke ziehen und mit einem Gummi befestigen. Damit ist Aqua In-Out zu 100 % Garnelensicher! Selbst Garnelennachwunchs kommt da nicht durch

Absolut zu empfehlen 👍 Hab es mir gekauft um das lästige Eimer tragen zu ersparen und bin mehr als zufrieden mit dem Produkt 👍👍

Der_Egger - German

Dieses Produkt ist eine absolut tolle Sache.

Noch nie war der Wasserwechsel so schnell, einfach und sauber über die Bühne.

Mit den beigelieferten Anschlüssen, passt das System an nahe zu jeden Wasserhahn.

Die Länge von Schlauch ist absolut ausreichend. Sollte man mehr brauchen, gibt es auch eine praktische Verlängerung.

Nie wieder würde ich einen Wasserwechsel ohne dieses System machen. :-)

Świetny produkt. Znacznie ułatwia podmiany wody. Już nie trzeba biegać do akwarium z wiadrami. Działa tak jak powinien i pasuje prawdopodobnie do wszystkich, tradycyjnych kranów. Używam bezproblemowo od ponad roku. Ważne jest, aby akwarium było nieco wyżej niż kran, bo wtedy urządzenie jest najbardziej wydajne, jednak radzi sobie również w akwariach umieszczonych dosyć nisko. Polecam :D
