JBL Artemio Mix: There are only very few nauplius larvae, or none at all, hatching in my tank. What am I doing wrong?
A water temperature of 25 °C is ideal for hatching. At room temperature (equivalent to a water temperature of approx. 20-21 °C), it takes up to 36 hours. Try again with 2 instead of 3 spoonfuls of the fermentation starter and reduce the air supply to approx. 50%. On condition that the best-before date has not been exceeded, this should work. An additional lighting source at the start of fermentation can considerably increase the hatching rate.
With reference to the KidsSet: the number of eggs in the KidSet in the salt mixture has been reduced (so that the hatched larvae don't poison themselves with their metabolic end products), and this means that you may not be able to recognise the small nauplii in the KidSet at first sight. Backlight may help to see them better.
Planktonic algae are ideal for rearing the larvae. ArtemioFluid contains a suspension of ultra-fine algae products which the larvae accept as substitute food. A warm, light spot is recommended. If there is a lack of light, especially in the winter, you may want to provide additional lighting, e.g. by using an energy-saving lamp.
