Product features

  • Perfect for the plant care in freshwater aquariums. Its porous structure promotes the growth of roots. Suitable for digging fish
  • Nutrient buffer with high iron content. Is capable of storing excess nutrients, to release them again when needed. The high iron content is absorbed by plant roots
  • Activates the soil flora by motivating the quick and effective colonisation of beneficial ground bacteria. This inhibits the growth of unwanted algae, reducing the work-load on the filter and ensuring crystal-clear water
  • Accentuates the beauty of the fish: its dark-brown tone highlights their colours and combines with the green and red tones of the aquatic plants to create a harmonious appearance
  • Ready-to-use substrate which needs to be rinsed once in tap water before use. Available in various packaging sizes

  • Are the initial rust flowers harmful to invertebrates?

    No, because the iron is already oxidized and no longer freely available in the water. Plants can reabsorb it through their roots if you do not remove the flowers completely or stir them into the soil.

  • Why do brown spots form on the floor after installation?

    JBL Manado Dark is a natural product. Initially, there may be a slight increase in iron content and hardness values. This will normalize after several water changes. Harmless iron blooms may occur in soft water. Rinse JBL Manado Dark briefly in tap water before use to remove any abrasion caused by transport. If iron flowers appear, there is no need to worry. They pose no danger to your invertebrates and fish. Plants absorb the iron through their roots. You can suck up the iron flowers with a fine air hose, stir them into the substrate, and change 50% of the water every other day for the first 10 days. This will reduce the effect.

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).

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.
