Natural products in the invertebrate aquarium
Especially bacterial diseases and fungal infestations in shrimp, snail, crab or crab aquariums can be well prevented with natural products. Their high content of humic substances and tannins, which are gradually released into the water, makes them very valuable for keeping invertebrates.
Humic substances and tannins make the skin more resistant and protect the mucous membranes. In addition, these substances can bind pollutants such as heavy metals in the water, making them harmless to shrimp, crabs, crabs, snails, mussels and fish; they also have a bacteria-killing effect and inhibit the growth of certain fungi. Furthermore, humic substances buffer the pH value at approx. 5.5 to 6.5, which is of great advantage especially in soft water aquariums. There, the carbonate hardness (KH) is missing, which would prevent a drop in acidity because it buffers the pH at 7 to 7.5. The presence of humic substances counteracts it just as reliably, and they keep the pH just as stable, but in a lower range. Bee shrimp in particular tolerate high KH values very poorly, and they need a lower pH. So the presence of humic substances is very beneficial for them. But even in community tanks operated with tap water with a higher carbonate hardness, products from nature such as foliage or alder cones can be used - their effect on the pH may not be given there, but their positive properties for the animals are still given, in addition, foliage leaves and alder cones look very natural in the aquarium, offer the animals a good hiding place and also serve them as a food basis.
Banana leaves, sea almond leaves or catappa, respectively, and alder cones are a well-tolerated way of introducing these substances into the water, especially for shrimps. Their effect is quite mild, but you should not overdose in any case. If the leaves or cones have lost their effect after some time, they are eaten by shrimps, crayfish, crabs and snails. Since they have no negative effects on the water, you can simply leave them in the aquarium until they are eaten.
If there is already a bacterial disease - for example, if shrimps keep dying or if the animals become whitish and cloudy inside - you should bring out some stronger weapons. In these cases sea almond bark or cinnamon sticks can be helpful. Please pay attention to the dosage! Again, once the active ingredients have been released, these products still provide highly welcome hiding places, and they are enthusiastically grazed.
