Quelle est la meilleure chose pour le fond d’un aquarium ?

Sand is always a preferred option for an aquarium. Sand gives a very natural look to the jar. Sand comes in a variety of shades of color and thickness. Most types of sand are inert and do not impact water parameters, unlike some gravels and rocks. Sand is the best option for snails, crabs and fish that like to bury themselves. The main advantage of sand is its smooth appearance and natural finish. The sand also keeps debris and trash from sinking into your substrate. Does your aquarium house freshwater invertebrates , cichlids or burrowing fish like Kuhli loaches? So, we advise you to choose sand as a substrate. Cependant, Gravel is the most common type of aquarium substrate and is an ideal product for most freshwater aquariums. Gravel is popular with freshwater aquarists for several reasons. First, it's perfect for raising almost any freshwater fish and most invertebrates. Gravel is also the ideal choice for growing aquatic plants, as it allows the roots to absorb nutrients from the water flowing through the substrate. Finally, it is easier to maintain a planted gravel aquarium than a sandy bottom aquarium. Additionally, gravel aquariums encourage colonies of bacteria and other ammonia-eating microorganisms to grow throughout the substrate.

Une règle de base est de partir sur une couche d’environ 4 à 5 cm de sol nutritif et de positionner par-dessus 3 à 4 cm de sable de Loire ou de quartz fin. Évitez les sables trop grossiers qui ne permettent pas aux racines de bien s’ancrer et maintiennent mal le sol nutritif. Plus la couche de sol nutritif sera importante et plus longtemps les plantes pourront puiser dans celui-ci de façon correcte sans nécessiter d’ajouts d’engrais liquides ou autres. Suivant la densité de plantation et les exigences des différentes plantes choisies ces épaisseurs peuvent varier.
