CHOOSING THE BED
 

CHOOSING THE BED

The bed does not merely serve an aesthetic function - it must also contribute to the overall balance of the aquarium. It is a living environment in which various physical, chemical, and biological mechanisms unfold in accordance with its composition and granule size. It is therefore important to make the right choice of material at the aquarium's planning stage, in order to satisfy all these requirements.
