JBL pH-Plus
Water conditioner to increase the pH and KH values in fresh and marine water aquariums

  • To adapt the pH value and the carbonate hardness to the needs of the fish and invertebrates in fresh and marine water aquariums
  • Rapidly raises and stabilises the pH value by increasing the carbonate hardness (KH)
  • Use in freshwater: can be used as often as needed to raise the carbonate hardness in too soft water to the desired value. Maximal increase of the pH value to 8.5
  • Use in saltwater: adjusts the carbonate hardness to the natural ocean value of 10 to 12 °d KH and thus adjusts the required pH value of 8.0 to 8.4
  • Package contents: 1 bottle pH/KH booster. To use: 10 ml/40 l water. Results in an increase of approximately 1° dKH and a stable pH value

Product information

Nature at Home – Home for Fish and Plants
Fish need to be as comfortable in the aquarium as they are in the wild. Water dwellers have adapted to the acidity (pH value) of their natural habitat and need to find similar conditions in the aquarium. The wrong pH value not only means stress for the aquarium dwellers but it also can be a cause of disease or reduction in lifespan. JBL water conditioners decrease or increase the pH level and make the water ideally suited to the requirements of the fish once more.

Benefits of the JBL water conditioners
Raise the pH value fast, stabilise by increasing the carbonate hardness.

Water chemistry for experts:
The carbonate hardness (KH) contains bicarbonates (HCO3)2, which stabilise the pH value. If the KH is too low, the pH value fluctuates strongly and is lowest in the morning. In the course of the day it rises and falls again overnight. Since the pH value is a logarithmic value, a decrease from, let’s say, 8 to 6 overnight means a hundredfold increase of the acid concentration! The carbonate hardness pulls down too high pH values or pulls up too low pH values and keeps it stable. This prevents too strong fluctuations. In freshwater aquariums the KH should never be below 5 °dKH. Only in Tanganyika and Malawi aquariums is it good when it’s higher. The marine water aquarium should have a KH between 7 and 12 °dKH, so that a pH value of 8-8.4 is adjusted automatically. Higher KH values make little sense and often lead to the problem of calcium precipitation. As JBL pH-Plus is based on sodium hydrogen carbonates and would permanently supply bicarbonate but no calcium in marine water aquariums, we recommend JBl CalciuMarin, which supplies both calcium and bicarbonate, for regular KH increase and pH stabilisation in those aquariums.

FAQ
How can I increase the carbonate hardness (KH)?

By adding a liquid KH booster, such as JBL pH-Plus, the pH value is stabilised by increasing the carbonate hardness (KH) and in marine water, for example, brought to the required target range of 8.0 - 8.4. The stabilisation should always be carried out in small steps spread over several days.

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.
