Product information

Air pump accessory for aquariums
At night an air pump with air stone is an advantage for the aquarium because plants without light don’t produce oxygen, but continue to consume it. In thinly planted aquariums the air pump with air stone supplies the necessary water circulation. In aquariums with dense planting the air pump provides the aquarium with oxygen at night, since the number of plants means the oxygen concentration can drop to a dangerous level. When disease is present in the aquarium the air pump increases the oxygen level in the water, which is essential for many medications.

Simple connection
Connect the air stone to the hose of the air pump (not included), place the air stone inside the pond or aquarium. The own weight of the air stone keeps it on the ground.

Technical Data

FAQ
How can I remove the hose from the device?

At first the air hoses and special CO2 hoses can easily be pushed on the connection piece. The hoses harden more and more as the months go on and can only be removed from the connection piece using great force. If you pull the hose hard it will only strain the connection, which could, in the worst case, even break off. Instead cut the hoses you want to remove laterally at the ends and carefully remove them. For this it’s always advisable to install hoses with some reserve in its hose length.

Does the use of bubble stones and a strong current expel the important plant nutrient, CO2, from the water?

During aeration and/or when there is a strong current, a gas equilibrium is achieved between the ambient air and the water. As a result a corresponding but very low CO2 content occurs too. BUT this low CO2 content is far too low to for most aquarium plants to thrive. The aquarium owner is therefore dependent on an additional CO2 supply by a CO2 fertiliser system. The higher CO2 content this achieves is reduced or, as commonly referred to in aquatics, expelled by the aeration and strong current. Therefore well planted aquariums should only be slightly aerated at night, if required.

PUSH messages from JBL

What are PUSH messages? As part of the W3C standard, web notifications define an API for end-user notifications that are sent to the user's desktop and/or mobile devices via the browser. Notifications appear on the end devices as they are familiar to the end user from apps installed on the device (e.g. emails). Notifications appear on the end user’s device, just like an app (e.g. for emails) installed on the device.

These notifications enable a website operator to contact its users whenever they have a browser open - it doesn’t matter whether the user is currently visiting the website or not.

To be able to send web push notifications, all you need is a website with a web push code installed. This allows brands without apps to take advantage of many of the benefits of push notifications (personalised real-time communications at just the right moment).

Web notifications are part of the W3C standard and define an API for end user notifications. A notification makes it possible to inform the user about an event, such as a new blog post, outside the context of a website.
