Il faut déterminer la profondeur du substrat nécessaire. La profondeur minimale recommandée est d'au moins 2 inches. Cette recommandation est également indiquée sur les sacs de fluorite.

Ever since I have been keeping a planted tank, about 20 years, it has been the consensus that the substrate should be at least 1.5 to 2 inches in depth. I have not seen anything to convince me that that is bad advice. But, has anyone done enough experimenting, either on purpose or accidental, to find out what happens when you don't have sufficient substrate depth? What is the effect on the plants? When troubleshooting, what symptoms go with inadequate substrate depth? This is for rooted stem plants, primarily, but rooted plants in general too.

Vous devez vous assurer que le substrat est à la bonne profondeur pour vos plantes d'aquarium. Il existe quatre groupes de plantes aquatiques qui peuvent être classées par type de racine. Les plantes à racines profondes comme Cryptocoryne et Echinodorus nécessitent une profondeur de substrat d'au moins 6 cm. Les plantes à racines profondes auront besoin de la plus grande profondeur. Si elles sont plantées dans un substrat qui n'est pas suffisamment profond, les racines deviendront emmêlées et les plantes d'aquarium souffriront d'un manque de nutriments. Le substrat doit être entre 3 et 8 mm d'épaisseur. Les granulés plus gros bloqueront la croissance des racines et les plus petits peuvent écraser les racines. Il est recommandé de mettre le substrat en phases, par exemple en mélangeant la première couche de fertilisant solide, puis en ajoutant deux couches supplémentaires de gravier avec les granulés les plus fins sur la couche supérieure. Pour vous donner une idée de la profondeur du substrat, vous devez considérer le type de plantes d'aquarium que vous allez utiliser.

40-50mm is about minium or 35mm at the front and 75 at the back might be a guid line but there is no real ‘one’ answer as most plants would probably prefer much more depth than we normally offer and people also use the substrate for appearance and or as part of the overall design. Then you have tank size, a big tank might look better with a deeper substrate ? Then perhaps you could say an Amazon Sword might require a lot more depth than a tiny foreground plant? So if you have 300lt tank with large rooting plants 75 -100mm or if you have 60l tank with carpet plants 25mm would work. A good 1.5-2 inches at the front for small foreground plants right up to as far as you’re comfortable at the back but ideally I’d say 10cm is minimum for stem plants. Giving plants a deep substrate to anchor unit would be ideal. If I could change anything on my tanks, I would add more substrate next time. I think 15% minimum of the height of the tank is about right. I think 70 mm is pretty good for whatever needs you have. Mine is about 6cms at the front and 10cms at the back.

Most planted tank keepers would agree that a depth of around 6cm is ideal for plants to develop healthy root systems. You can have very thin substrate in areas but a lot of plants will not root into these areas and will continuously float out, so plan the layout of your plants carefully if you want to have shallow areas. Can substrate be too deep? Short answer – not really! You just need to make sure you set it up correctly, and don’t mess with it! The larger grain size of aquasoil also means it does not compact easily which allows for easier penetration by roots. If you’re using an organic soil, to create a “dirted” tank, ensure you cap your soil level with several centimetres of finer sand or gravel to ensure all those decomposing organics don’t leech out immediately into your water column.
