Product information

Nutrition for aquarium plants
Healthy plants are important for every aquarium. Plants supply the aquarium with vital oxygen for the aquarium dwellers, prevent algae growth and remove pollutants.

Healthy plants = healthy fish
Healthy plants prevent algae growth, supply oxygen, remove pollutants, provide hiding places and reduce pathogens.

For the plants to flourish the following demands need to be met: Light as energy source for the photosynthesis of CO2, nutrients and trace elements as growth promoters.

JBL fertilisers supply the plants with all main nutrients and essential trace elements through the water. This way the plants can absorb all the required nutrients they need over the leaves and roots.
The capacity of a CO2 system depends on various factors. The carbonate hardness, the quantity and species of the plants and the strength of the water surface movement are decisive.

FAQ
Can the 1200g disposable cylinder also be used with the older JBL CO2 systems?

Yes, this is possible without any problems. The JBL PROFLORA CO2 CYLINDER 1200 U also fits the older pressure reducers of the JBL PROFLORA u range.

Bluish discolouration despite increased CO2 supply

Owing to a production fault a green colour change may not occur with the batches 1000 and 1001, despite increased CO2 supply.

Should you have one of the above mentioned batches, you can request a new refill set free of charge upon presentation of the sales receipt and a photo of the batch number. Please contact our customer service under: https://www.jbl.de/support/

Is it bad if water runs into the bubble counter?

If water runs back into the bubble counter, that’s not a problem as long as the water is not drawn towards the night time shut-off from there. The excess water is normally pressed out of the system again during the day.

JBL ProFlora m500: What is the range of a 500g CO2 cylinder?

There is no general answer to this question, as we do not know what the desired number of bubbles for your aquarium is. One bubble contains approx. 0.125 mg CO2, which corresponds to 4 million bubbles for a 500 g cylinder. At a consumption of 10 bubbles per minute (600 bubbles per hour), this corresponds to 6667 hours, which in turn corresponds to around 277 days or slightly longer than 9 months of unchanged CO2 supply.

Please note that this is a rough estimate and does not represent a guarantee about how many days you can actually get out of one compressed gas cylinder.

Where did my algae come from?

Algae problems in an aquarium can never be traced to just one factor or general condition, and instead, are always the result of a combination of different factors, which include light, fertilization, water changes – specifically, how often and how much – feeding, fish population and, of course, the specific water parameters.

According to analyses that were performed over a course of a number of years, red algae, at least the common brush algae and beard algae, occur in descending order at the following parameters:

1) too little carbon dioxide (in relationship to 100 % of the measured tank); the pH level should be in the slightly acetic range, depending on the carbonate hardness, in every case.
2) elevated phosphate levels (over 90 %); phosphate limitation by means of JBL PhosEx ultra is often helpful here.
3) too little and too irregular fertilization (there should always be traces of iron at least).
4) insufficient water changes; a weekly water change of over 30 % is recommended for algae problems.
5) not enough fast-growing plants.

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.
