The JBL Professional Test Kit for Koi Specialists

JBL enters the market with a brand-new JBL Testlab for Koi, perfect for the start of the upcoming pond season. Ten highly precise water tests enable koi enthusiasts to conduct quick and exact water analyses. JBL Testlab Koi in den Handel, passend zum Start in die kommende Teichsaison. 10 hochpräzise Wassertests ermöglichen dem Koi-Freund eine schnelle und exakte Analyse des Wassers.

Since koi ponds tend to have no vegetation and contain many fish that are fed regularly, the increased levels of phosphate consequently cause a problematic increase in algae of up to 10 mg/l. The completely new JBL phosphate test for koi fish shows values between 0.1 and 10.0 mg/l so that initial counteractive measures can be taken. Only once the phosphate value is reduced to values under 2.0 mg/l by a phosphate remover such as JBL PhosEX Pond is it possible to change to the JBL Phosphate Test Sensitive which also registers lower values between 1.8 and 0.02 mg/l. Both tests are contained in the JBL Testlab for koi.

Due to the high pH values in koi ponds, an ammonium/ammoniac test is included in addition to the adequate pH test. When the pH values are high, an increasing proportion of the nontoxic ammonium turns into acutely poisonous ammoniac. The following nitrogen break-down stages of nitrite and nitrage can also be precisely determined with tests.

Tests for determining carbonate and total hardness continue to be part of the kit. Especially koi enthusiasts regularly test the total hardness since a low mineral content in the water can lead to hole-in-the-head-disease-like phenomena. With algae problems the contained oxygen test can indicate whether the oxygen depletion, which appears at night due to algae, can be hazardous to the fish and aeration will become necessary.

All contained JBL water tests are insusceptible to water temperature and provide a correct reading between 4 and 35°C.

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.

JBL GmbH & Co. KG provides this service free of charge, and it is easy to activate or deactivate.
