Laterite is an ideal lower layer or substrate for planted aquariums.
The commercial substrates are packed and labeled for the type of aquarium you need and include detailed instructions.
Keeping, maintaining, and ultimately propagating your aquarium plants is truly a joy, and it starts with a good substrate. The term 'substrate' refers to the planting medium used on the bottom of an aquarium. Similar to soil in a garden, substrates are needed by plants in order for them to root, obtain nutrients, and propagate.
There are several things to take into consideration when choosing your planting medium. Which types of substrates to use are determined by: Determining what type of substrate to use is extremely important for the plants. For healthy aquatic plants, the substrate provides nutrients for normal plant growth development and plant propagation. Several substrates available in most stores include: common pea gravel, aquarium gravel, sand, nutrient-rich and soil-based substrates, clay substrates, and quartz gravel (lime-free gravel). Often, different substrates can be mixed to obtain an optimum environment for your particular types of plants.

Aquarium Set-up: How Much Substrate Do I Need for my Aquarium?
The advantages of decorating a fish tank with live plants instead of plastics are numerous.A healthy planted aquarium is essential to maintaining a population. Most importantly, plants contribute to balancing the oxygen level and algae growth while providing hiding places for fish. However, it is hard to cultivate plants in an aquarium because it requires some effort. Plants need lighting, water circulation, and good aquarium substrate to grow healthy. Substrate is the medium where plants and beneficial bacteria grow due to the rich nutrients. Each plant requires different care and each substrate type depends on the plant species in the tank.Ordinary aquarium gravel consists of smallchips of granite, basalt, and other non-calcareous stones. There areseveral reasons why it has become the standard substrate for mostaquaria, but the most important is that it is chemically inert and sodoes not affect the hardness or pH of the water. This means that it canbe used in soft water aquaria without any risk of it slowly dissolvinginto the water and thereby raising its alkalinity. Another importantfactor is that gravel is relatively coarse and irregularly shaped,making it an excellent filter medium when used as part of an (a rather misleading name perhaps,given that the filtration is in, not under, the gravel!). Compared withcanister filters, cleaning undergravel filters couldn't be easier-- every month or two rake the gravel with a stick and siphon up themuck that comes out. The aquarium substrate acts as a natural filter by collecting the organic waste that falls down; is a source of food for the aquarium plants, and imitates the natural fish habitat.Substrate colors can range from natural ones to shocking neon colors to dark colors. The choice is entirely up to you, depending on what you prefer, what will compliment your fish, and the theme of your aquarium. Just a quick reminder: , so choose wisely. Lighter substrate will work wonders for darker colored fish and darker substrate will do some color enhancing for lighter colored fish.
