  • What happens, when Denitrol has been dosed and the animals aren’t added until several days later?

    If you don’t immediately add your animals, the cleansing bacteria included in Denitrol will quickly die from lack of food. If you wait a few days before adding the animals (against the advice of these instructions) problems will occur with ammonium/ammonia and nitrite. In the end, the bacteria will not be able to develop and will die off due to a lack of food. As a result the ammonium excreted by the fish will not be broken down. Since no bacteria are present to oxidise ammonium into nitrate in two steps, a nitrite peak will occur despite the application. If the first fish are introduced immediately after the addition of Denitrol, the purification bacteria get food and begin to multiply. This is comparable to an unathletic person who starts doing sports and first has to "train up" his fitness. This ensures that there are enough bacteria right from the start and that neither ammonium/ammonia nor nitrite become a problem when more fish are added. Please always increase the fish stock moderately and only after a few days.

  • Do the "filter bacteria" pose a risk to sensitive persons, as they could potentially be transmitted by air?

    No, these bacteria are generally harmless to humans. _x000D_ They can not get into the air, as nitrifying bacteria are generally substrate bound and bound to a medium that is aqueous to at least moist.

  • How are the filter bacteria (nitrobacter) preserved in the bottles? How can the bacteria survive inside?

    The bacteria in the products are contained in a nutrient solution which meets the "minimum requirements", as full-scale metabolism would shorten the shelf life. As long as the bottles are in their original packaging and stored at temperatures between 4-35 °C the shelf life is 18 months. _x000D_ _x000D_ If the liquid is clear or has occasional small brownish flocks, the product is fine. The smell should be barely discernible. If the liquid smells of rotten eggs or if it contains black flakes, the product is no longer suitable for use.

  • Can I overdose Biotopol or Denitrol?

    Do not exceed the double dose of Biotopol. With Denitrol you can add up to five times the amount of a dose.

  • High nitrite value - addition of bacteria and effects

    When JBL Detoxol is used free ammonium is bound in the water, which provides immediate relief for the fish. This removal of ammonium also prevents any further nitrate from forming. Any nitrite already present is not bound. If you have high nitrite values, carry out a water change beforehand. A subsequent addition of bacteria will help you maintain a sustainable and biological removal of ammonium and nitrite.

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.

A notification makes it possible to inform the user about an event outside the context of a website, such as a new blog post, a competition or a voucher.

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).
