HOBBY Protogen - infusoires 20ml

To facilitate feeding of fry with live infusoria such as ciliates, paramecia, slippers, euglenoids and protozoa.
Hobby Protogen is a concentrate grown on fertile soil with dried infusoria of different sizes, which, in conjunction with water, revive in a very short time and continue to grow.
The aquarist is therefore able to feed the fry without difficulty.
There is no need to feed the Protogen infusoria, simply start a new culture every 3 or 4 days.
The presence of infusoria is most easily detected during feeding, if the fries converge at the point where the liquid has fallen into the water. Infusoria are not visible to the naked eye and only become visible at a magnification of 25 to 50 times.
The appearance of a skin on the 3rd day is possible if the Protogen broth was prepared in too large a quantity.
The presence of chlorine or drug residues in the culture broth prevents the formation of infusoria.
