While regular Amazonia and the Amazonia Light soil share similarities, there are some differences. Amazonia Light is made specifically to stop nutrients from leaving the soil and escaping into the water. It also inhibits algae growth in your planted tank.
Perfect as a top layer substrate
Both products greatly reduce Ph levels, and both materials contain nutrients that will make your plants grow. Yet, as the name suggests, the Amazonia Light is a little light on the nutrients.
With a reduced amount of nutrients, this makes it easier for beginners to use this product. You will have less cloudiness in the tank and, as a result, less algae growth.
This soil can be used on its own. However, the company recommends putting this on top of its regular Amazonia soil for better growth outcomes.

With Flourite, you won’t have to keep replacing the gravel. This product will never disintegrate and can stay in your tank for years and years. Your plants will be able to set roots and grow without being disturbed by a substrate replacement. The only real issue with this product is the lack of nutritional value.
Able to absorb and store nutrients
Flourite doesn’t come with much to feed your plants. You will have to buy fertilizer or root tabs. The root tabs might be your best option really. While there are not a lot of natural nutrients provided, Flourite is able to absorb and store nutrients. They do this better than most substrates. In this way, your plant will grow well when the right nutrients are added.
Keep in mind that Flourite lacks any water conditioning so it won’t help with your Ph levels if that is something you are looking for.

Another good thing about Flourite sand is that it provides more nutrition than other Flourite products. You shouldn’t have to buy fertilizer or other additives for this product. Still, it doesn’t hurt to have them on hand. Eventually, the nutrients will run out.
Liquid fertilizer can be a good option to add to your sand. Nutrition lost happens with most substrates though so it’s not something to worry about.
Unlike other sand substrates though, the Flourite sand will not disintegrate. It lasts for a long time and won’t need to be replaced. For this reason, anyone looking for a good sand substrate should consider this product. As a sand-based material, it is the best substrate for planted tanks!

The Importance of Substrate in Planted Tanks
One major benefit is produced on the surface of your substrate. With the right water care practices, substrate can become the site of beneficial bacteria growth.
Good bacteria can help filter your water and transform toxic substances into nutrients. These nutrients can then be used by your plants as a means of sustenance. In this regard, substrate is extremely important for people who put plants in their tank.
Substrate not only improves your water quality but helps feed your tank plants. This process will help your plant stay alive in the water longer.
Perfect landing place for plant roots
Substrate also achieves this aim with another ability. With the amount of materials available, tank substrate is the perfect landing place for your plant’s roots.
The varying surfaces of substrate will help your plant set firm roots in any tank. These roots prevent plants from floating aimlessly in the water and wilting.
Roots are the only way plants can take in nutrients. In planting flora in substrate you can give roots direct access to nutrients. Some substrate is able to store key nutrients for plants, and release them to the plant.
Overall, without substrate, most plants would cease to thrive and grow to their full potential in tank water.
Types of Substrate Commonly Put in Tanks
As we mentioned previously, substrate comes in many varieties. A number of materials are crafted to generate this unique product. As you can imagine, each of these different types of substrate serve a different purpose.
Gravel is the most common of all substrates. It is usually bought by beginner fish tank owners in local pet shops. Though this material is equally useful to people of all experience levels.
Gravel in fish tanks is made smooth enough and small enough to keep your fish free from harm.
These small rocks come in plenty of forms. You can find ultra colorful gravel or more muted gravel. Gravel that is rounded or gravel that is roughly shaped.
You can also find bigger pieces of this product or gravel that is micro-sized. The range in this product makes it extremely popular.
Another popular option for planted tanks is sand. Sand substrate is not only great for planted greenery in your tank, but it can also be good for certain fish. For example If you have a pet that enjoys digging into the bottom of a tank try sand.
Fish that like to cover themselves up, will be equally suited to this medium. This also applies to fish who like lower Ph levels. Sand easily balances out Ph in a planted tank.
Some types of sand substrate, like coral sand, have the ability to balance out the chemistry of your water. This can be helpful if you need to adjust the Ph of your fish’s water.
The only problem with this medium is the possibility of filter blockage. Small bits of sand might get stuck in the filter. So if you get sand make sure your hardware can handle this substrate.
Marble is another kind of substrate you can purchase if you want to affect the Ph level. But it isn’t nearly as efficient in planted tanks as sand substrates.
Marble has other beneficial qualities. It can be especially good if you want to breed fish in your tank. The gaps this material creates will help protect and house fish eggs in the water well.
Moving on, the last kind of substrate we will introduce you to is a complete substrate. Also commonly referred to as soil substrate. This type of substrate is considered to be a top-choice substrate for planted tanks.
Soil substrate is a great way to give your plants the nutrition they need. This substrate type is well compacted. This will help your plants root well without any issues. Most people with planted tanks choose this type of substrate for good reason.
Some people even choose to combine substrates to create an even better base for their plants. Putting gravel or sand under or over your soil base can help plants grow even better.
You can even create three layers for optimal growth.
How you choose to set up your substrate is up to you though. You might want a more natural look with sand and some soil. Or maybe you want your fish to stick out in a colorful tank filled with neon gravel.
What plants you have will ultimately determine which set up will work the best for you. Some plants have more specific substrate needs than others.
Amount of Substrate to Add
The amount of substrate added into your tank will depend on a few factors. One important consideration is the size of your tank. The bigger your tank is the more substrate you will have to purchase.
At a minimum though, and this goes for any tank, make sure you put in at least one inch of substrate.
For planted tanks, you want at least three inches of substrate. If you want an even more concrete number, most people use the following formula.
For every one gallon of water, you will need to add in around a pound of substrate. With this, you can pretty accurately estimate the exact amount of substrate to add into your tank.
This isn’t a foolproof method though. The shape of an aquarium also has some impact. Tanks can be longer or wider and this will also affect the amount of substrate required.
Three inches of substrate in a wide tank will amount differently to three inches in lanky portrait tank. And then there is your plant’s need. This should be the biggest metric of measurement. If your plant has to root itself deeply you will need to get more substrate into your tank.
Choosing the Best Substrate for Your Planted Tank
The quality of your substrate is crucial for planted tanks. You do not want to put your greenery into low-grade material. In addition, the substrate should fit the needs of your plant. What substrate your tank will require depends heavily on your plant’s disposition.
Many plants use roots as a means to feed themselves. Thus, a nutrient-rich substrate is considered a great option for many planted tanks. Also, if your plant needs to root deeply into something then soil is definitely a plus.
Still, the best material can depend on the type of planted tank you are building. Not all plants have the same demands.
The water in your tank should also be a factoring quality when looking for a substrate. Some material works better in saltwater. Other substrates are only meant for freshwater tanks. Consider this when you make your product choice.
Lastly, you should think about how you want to mix and match your substrate. Some people just prefer to put soil substrate down by itself. This method can make for a perfectly simple setup.
But as we talked about before, layering substrate can also be beneficial. If you put gravel or sand substrate on top of the soil you’ll keep your soil from floating into the water.
This type of layering is known as a composite substrate. If you think your soil is too loose, or notice it coming apart try out this method. Sometimes it can take experimentation with multiple substrates to find the best one!
Color And Your Substrate
Color is something else to consider when deciding to purchase substrate. Some people argue that unnaturally colored substrate is indicative of a lower quality product. This isn’t the case at all.
Many fish owners debate over colored substrate. In reality, the color of the substrate you get all depends on your preference.
What you want to do with a fish tank matters the most in this choice. If you are trying to recreate your fish’s natural environment then go for a more earth-toned substrate.
If you want something a little more colorful and fun than that’s fine as well. There are plenty of multicolored gravels and rocks to pick from.
Just make sure the substrate you use is right for your plants and your tank. Your plant and your fish’s health is more important than any aesthetic look you might be going for.
Maintaining Your Substrate
Tanks need to be cleaned out thoroughly to keep your fish healthy. This also includes the substrate in your aquarium. The level of cleaning for each substrate differs substantially. How much you put into your tank can also make this process longer or shorter.
Keep in mind that certain substrates will need to be rinsed down before they go into your tanks.
Material such as gravel can be lightly suctioned with a vacuumed. All of the dirt and waste left in-between the gaps of gravel need to be removed. If you chose to use sand as a substrate clean up shouldn’t really be an issue though.
Waste doesn’t get as easily trapped in sand. But if you do see some debris you can use a small net to get rid of it. Really, you don’t want to disturb the surface of your substrate too much. There are a lot of good bacteria growing at the base of your tank.
Some substrate will have to be replaced eventually though. This is true for soil-based substrate. The nutrients in your soil-based substrate will eventually get used up. You could replace the soil completely, but there is an easier option.
To replenish the nutrients on the surface of the soil use some liquid-based fertilizer. You can also add in root tabs for extra nutrients. This option is a lot less of a hassle overall.
Table could not be displayed.
Substrate is a product that comes in a variety of mediums, shapes, and sizes. Each substrate offers its own specialized properties and uses. Substrate not only makes a tank look more complete but helps improve the ecosystem of an aquarium.
Which substrate you will need is contingent on the plants and fish in your tank. Some substrate is better suited for planted tanks than others.
