Amtra Log Cabin on Rocks

Very nice decoration for your aquarium.

Aquarium water should not remain undisturbed under decorations for too long, but always be involved in the "biological" cycle.
In order not to accumulate too much still water in large objects, you should consider installing an air stone with a diaphragm pump underneath. This not only ensures enough circulation but breathes new life into your dream project! Your fish will be happy about the extra dose of oxygen!

Plastic can be processed easily and quickly!
If your deco object does not have any openings, you should consider drilling small holes in it to feed an air hose inside to provide the necessary water circulation.
