How deep substrate for planted aquarium

How much is the substrate deep? It is an interesting question. However, substrate deep doesn’t rely on aquarium size. We should keep a minimum of 2 inches deep substrate in our fish tank. It also varies on different types of substrates. But a suitable deepness of substrate is quite a positive factor for our fish tank.

Type of cheap substrate for planted aquarium

There are three varieties of substrate we can use in our planted aquarium. Those are gravel, sand, and soil. Gravel is one of my preferred substrates to use in my fish tank. Gravel is included nutrients and is also cheap. In addition, its ingredients have different sizes and colors. But it has some downsides also like; it needs a daily wash, and sharp gravel can create problems for fish.

On the other hand, sand is the cheapest gravel among all. Sand also has different sizes and shapes. And sand is an excellent substrate for the bottom feeder. But it doesn’t contain many nutrients compared to others. And also, it is not good for live plants.

Soil has the potential nutrient combination, and it is excellent for live plants and tropical fishes. But it is not cheap compared to other substrates, and it does not have different sizes, shapes, and colors.

Conclusion

So we don’t need a lot of money for our substrate for planted aquariums. If we properly plan our work for choosing the substrate, we can save a lot of money. Substrates are going to vary depending on what plants we are utilizing in our tank. So different plants require different substrates to grow.
