Best Gravel for Aquarium

What’s the best aquarium gravel on the market?

Aquarium gravel is one of the decorative elements of the aquarium, which I personally consider the most useful.
Not only does it have an aesthetic function, it is also the perfect place for beneficial bacteria to flourish, as well as making cleaning the bottom of the aquarium much easier.
In the market there are a good number of gravels for sale, some with very attractive colors, which can highlight the natural colors of our fish or prawns.
I wanted to create a comparison, with the different types of aquarium gravel, so that you can choose more easily, I hope this comparison will be useful to you.

Types of gravel for aquarium: Best quality price aquarium gravel

The gravel that is usually used in the aquarium is quartz, neutral , which does not have the ability to alter the parameters of the water, neither the pH, nor the GH.
But you can also buy calcareous gravels, which increase the GH and KH of the water , ideal for use with African cichlids , avoiding having to artificially increase the hardness of the water.

What is better aquarium sand or gravel?

One of the typical questions among beginners is whether it is better to use silica sand or gravel . Silica sand is this finite sand and it is fantastic in decoration, just like those on the beach.
I think the first thing that should be done is to differentiate what is one and the other.
The sand has a gralumetry or grain size of 1 mm , more or less. While it is considered gravel when the product has from 2 mm to 5 mm.
In aquarium the gravel is usually between 4 mm and 5 mm.
The sand aquarium is much more decorative than gravel, but is compacted too much.If our idea is to have a planted aquarium, in which we are not going to introduce any nutritive or clay substrate (typical of densely planted aquariums), it is best to use gravel.
There is a very simple reason, the roots of the plants will develop perfectly in a gravel substrate , but it will be impossible in one of sand.
If you want to use sand for decoration, there are options, such as putting the plants in pots or mixing gravel and sand, although this last solution may not be the best … unless they are of a different color.
