FAQ
How do I properly open/close the CO2/pH permanent test diffuser?

To open the CO2/pH permanent test diffuser (angled model with black stand) just pull at the transparent cover with a sharp tug. The lid fits very tightly to prevent the diffuser liquid from leaking into the aquarium. To easily close the CO2/pH permanent test 2 diffuser (round model with white back) we recommend lubricating the seals with JBL SiliconeSpray. It is advisable to attach the lid in a tilted position and to press firmly against the bottom for 3-5 seconds to make sure that the rubber seal slips inside. Otherwise you can repeatedly press in “pumping strokes”. This ensures that the seal does not slip off and the diffuser liquid does not escape into the aquarium.
Both instructions apply to all batches manufactured until 10/2016. Subsequent models are provided with a modification which reduces the described effect if problems occur.

Despite CO2 fertilisation the indicator remains blue

No CO2 is generated when fertilising with so-called liquid carbon. Therefore the test is not able to indicate CO2, which means that the indicator always remains blue! If you add CO2 in gas form you need to increase the amount or the duration.

JBL CO₂/pH-Permanent: Does ozone affect or distort the measuring of the CO2 permanent test?

Depending of the dosage it is quite possible that the ozone attacks the indicator of the CO2 permanent test and “oxidizes”. A reasonable continuous measurement of CO2 is then not possible with this method.

Is the fluid of the JBL CO₂/pH-Permanent Test harmful to the tank inhabitants if some of it gets into the water ?

The fluid itself with the colour indicator is not harmful in any way with the high dilution in the tank and, in addition, it decomposes very quickly.

Do my water tests still work although they have been open for nine months?

Basically a sealed test keeps longer than an open one. How much the shelf life is reduced depends crucially on the handling and the storage conditions of the reagents. It may happen that a reagent in a test that has been open for 9 months doesn’t indicate correctly any more. However, additional information is needed to answer this question properly.

Why is carbon dioxide (CO2) the most important plant nutrient in the aquarium?

Carbon dioxide is the nutritional basis for aquatic plants which is supplemented through micro and macronutrients and light. The balance between all these elements is necessary for thriving plant growth in the aquarium.

There’s more to fertilization than you’d think Part 2

Simply put, Liebig’s Law of the Minimum states that the growth of plants is limited by the scarcest resource. Adding a nutrient which already exists in abundance does not influence the growth.

Fertilization is not just fertilization Part 1

Unlike in natural waters, aquariums with fish mostly have a surplus of nutrients caused by feeding and the resulting fish excrement. Thus nitrates and phosphates in large (often too large!) quantities are available for the plants.

Why are you letting your plants starve?

EVERY aquarium plant needs carbon dioxide (CO2) to survive and to grow! Fast growing species especially need a lot of CO2, and red fish species need CO2 fertilisation to survive.
