Suppose you’re putting together a planted aquarium. In that case, you’ll want to provide the best environment for the plants to thrive, and substrates can help with that.
They come in a variety of shapes and sizes, but it is critical to use the best. Some people use sand, gravel, potting soil, peat, clay, and even small smooth rocks.
The best substrate for planted aquariums is essential because it can mean the difference between an average tank and a beautiful aquarium. Some plants require rich substrates to thrive, while others are column feeders.
In this article, we will discuss the best substrate for providing maximum nutrients to your aquarium plant. So, let’s start with the question: What should be considered before buying substrate for my planted aquarium?
The substrate in a planted tank should be able to store and supply nutrients to the plants. The vast majority of nutrients should be found in the gravel rather than the water column. The root system should be where plants get their nutrients and minerals.
Suppose they are planted in the shallow substrate. In that case, the roots will become entangled, and the aquarium plants will suffer from nutrient deficiencies. Your best substrate option may be a combination of Aqua Soil and Seachem Gray Coast, an aragonite-based substrate rich in the missing ingredients.
The last thing you want to do is lower the pH and soften the water, so avoid nutrient-rich substrates as much as possible. Now, my friend, we are just getting started.

2. UP AQUA Sand for Aquatic Plants
You can avoid this problem by using the UP Aqua Sand Substrate. Because it does not discolor the tank’s water, you can use it directly in your tank without washing it. This is ideal for many aquarium plants because it provides a suitable substrate for their roots to grow in.
It is dense enough to keep roots in place, but it also has enough space between grains to allow roots to spread out and absorb nutrients properly.
The substrate reduces the pH to a range of 6.5 to 7.0, completely neutral or only slightly acidic. This pH range is ideal for a wide variety of fish and aquatic plants.
There will be no clouding of the water after the tank has been filled. This is truly amazing how clear the water will be right after the tank had been filled. Because the nutrient-rich nature of this substrate has resulted in healthier plants, you can see good root development.
Another significant advantage is that this material does not need to be cleaned before use, which is not true of most other sand-based substrates.
- Longevity is excellent.
- Lightweight and conductive.
- It is a good source of nutrients.
- Lowers the pH of the tank.

3. Fluval Stratum Plant Substrate For Fish Tanks
This substrate is ideal for you if you have an aquarium for plants and betta fish and shrimp. This product is made from organic volcanic soil that is naturally mineral-rich. Volcanic soil contains many unique components that set it apart from other types of soil.
This aquarium substrate for live plants ensures the natural growth of aquatic plants by allowing the roots of the plants to spread deeply into them and absorb nutrients efficiently.
Fluval Stratum is ideal for freshwater shrimp tanks because it encourages algae and other tasty bits. As a result, shrimp will spend their days picking off these algae, and they appear to prefer it over other substrates. Another exciting feature is that its unique blend naturally lowers the pH of your tank to optimal levels.
These qualities facilitate the growth and development of nitrifying bacteria in the tank. These bacteria will aid in keeping the water’s health and cleanliness at peak levels.
- Soil rich in minerals from volcanic activity.
- Plant growth and root development are greatly helped.
- Lightweight and porous.
- The pH ranges from neutral to slightly acidic.
- Promotes a pH range of neutral to mildly acidic.
- It is appropriate for live plants or shrimp.
The things that might be bothering you: Because of the lightness of this substrate, it usually takes a few days to settle down and should take time to back to the normal condition of your water.

Frequently Asked Questions
Is sand or gravel better for a planted aquarium?
For most freshwater aquariums, gravel is a better option. They also come in various colors, allowing you to personalize your tank and match it to your fish. Sand does not allow water to flow as freely as gravel does.
How often should you change the aquarium substrate?
You should change the substrate every 18 months or whenever you are in danger of getting into trouble by keeping the PH at a high level.
What kind of filter should I use for a sand aquarium?
Use a pre-filter made of foam or a sponge. A coarse sponge will help prevent sand from entering your filter’s intake while not interfering with the filter’s flow.
How thick should aquarium sand be?
Simplified Reefkeeping author Robert Metelsky recommends a thickness of 1-3/4 to 2 inches, which is about the average depth used in most saltwater aquariums.
An aquarium necessitates a perfectly balanced environment, which can be challenging to achieve; as a result, you must find a suitable substrate. When you provide excellent microorganism(s) for your aquarium water, the substrate will keep your water clean and maintain a pH level.
Today each type of substrate has its own distinct features. They are portable, user and environmentally friendly, and easy to use.
