  • Why are there different recommendations and values on the colour chart of the water test?

    With the JBL PROAQUATEST drop tests you have a laboratory comparator system which compensates the inherent colouration of the water and at the same time enables non-chemists to carry out an accurate and safe water analysis. To ensure that water testing monitors the life of your fish and provides the greatest possible safety, you will find an evaluation adaptable to three different applications. _x000D_ _x000D_ Above the different coloured measuring points are numbers, three symbols and a colour band for each. _x000D_ _x000D_ The symbols stand for the following applications: _x000D_ Fish = freshwater _x000D_ Koi = garden pond _x000D_ Starfish = marine water _x000D_ _x000D_ The colour band tells you the meaning of the value determined in green (everything OK), yellow (attention) and red (need for action). In addition you will find numbers that reflect the value in mg/l for the respective colour field. _x000D_ _x000D_ The first two (freshwater and pond) colour bands belong to the upper number row. Marine water belongs to the lower number row. _x000D_ _x000D_ Why do the values differ? _x000D_ Due to the high salt concentration in marine water, the colouring of the reaction is not as intense as in freshwater (which also includes pond). Consequently, the value for the same colouration is greater than in freshwater _x000D_ _x000D_ Why do the recommendations differ? _x000D_ Every habitat reacts differently to certain nutrient concentrations. In the garden pond, for example, constantly changing temperatures and light intensity can jeopardise the value more than in freshwater, where, unlike in the pond, these factors are constant and necessary additives are supplied. That’s why the recommendations are green for one area of application, yet yellow for the other._x000D_ _x000D_

  • Does the oxygen test O2 flocculate slightly after the addition of the 2nd reagent?

    Yes, this is possible and normal (formation of manganese dioxide). Please shake the test vessel thoroughly before referring to the colour scale.

  • Where can I find the record sheets for the documentation of my water analysis?

    Have you lost your record sheets, used them all up, or need them in another language? _x000D_ In the appendix of this FAQ you will find PDF files for printing them out in German, English and French.

  • I have lost my colour chart. Can I download the colour chart for the test?

    The colour cards are not available for download on the JBL website. The absolutely accurate colour reproduction that is required can only be achieved using a printer which can be re-calibrated before each printout. Most privately used printers are not accurate enough for this. _x000D_ _x000D_ You will find the colour chart bundle as a spare part on the respective product page and in the spare parts shop under: https://www.jbl.de/en/products/detail/8732/jbl-proaquatest-assortiment-color-chart

  • Does the old O2 test work with the new refill sets?

    The new PROAQUATEST O2 Oxygen _x000D_ Each has now 3 instead of 2 reagents. Therefore, the appropriate new colour chart with red tones instead of beige tones must be used for colour comparison._x000D_

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.
