Flourite vs Eco Complete: Choose the Right Substrate!


What is your favorite kitchen appliance? For most of us, it’s a mixer. Most mixers use metal blades to stir batters and doughs during the mixing process, which can create some serious wear on these surfaces over time. One solution for this problem involves using ceramic or glass-based ingredients in place of metallic ones that are commonly used in modern day baking tools and appliances.

Flourite is a type of volcanic rock that is often used as a substrate for growing plants. It has been found to be a very beneficial substrate because it provides the perfect conditions for plant growth. Eco Complete is an alternative to flourite, which can be used in its place.

Fish tanks, on the other hand, may be both relaxing and challenging.

Still, who doesn’t like a little bit of beauty in their lives?

And we’re well aware that we’ll have to put in some additional work to create the ideal environment for our fishy friends. One of them is selecting the proper substrate or tank gravel for aquarium plant feeding and water filtration.

Is picking the right substrate, on the other hand, that simple? More importantly, which of the several substrates should you choose?

Oh, hello there! Don’t be afraid! We’ve already done some research on flourite vs Eco-Friendly and have your back. Moving ahead, we’ll go over all of the qualities of these two substrates as well as any potential variances. At the end of the day, you’ll have a clear winner in mind.

So, without further ado, let’s get started!

What Are the Benefits of Using Substrates in an Aquarium?

Before we talk about why we need a plant substrate, it’s important to understand how substrates operate. Substrates may be helpful in a variety of situations. From nutrition to looks, there’s something for everyone. In a nutshell, substrates are really beneficial to your aquarium!

A substrate, in layman’s terms, is a substance that is put at the bottom of an aquarium. They totally cover the tank’s bottom. Substrates are often made up of a combination of natural and manmade elements. 

Substrates are essential to the tank’s health. They play an important function in your tank’s nitrogen cycle. As a result, the development of beneficial bacteria is aided. In addition, the substrate aids the aquarium plants in obtaining nourishment.

They’re essential for your fish’s environment. The substrate is crucial if you have burrowing creatures such as snails or bottom-drawing animals. It provides a location for them to relax and search for any residual food. 

Finally, substrates contribute significantly to the overall beauty of your aquarium. For both you and the fish. Fish, for example, want an environment that is comparable to their natural habitat. The substrate mimics the appearance of the natural environment in the tank.

As a result, it goes without saying that substrate is critical to the health of your tank. However, selecting the appropriate substrate is critical! Continue reading to learn how to choose the finest substrate for your aquarium!

Fluorite vs. Eco-Friendly: A Comparison 

Now that we’ve covered the essentials, we can go on to the meat of the discussion. Flourite and Eco-Friendly are also excellent substrates for the purpose. They do, however, have a lot of essential distinctions. 

As a result, they may be used in a variety of tanks. Before purchasing any of them, it is necessary to understand their details. Everything you need to know about them is right here:

Substrate Composition 


https://aquariumadviser.com/ is a good place to start.

What’s the material you’re working with? When it comes to selecting a substrate, this is a critical consideration! Let’s talk about the Flourite and Eco-Friendly materials.

Fluorite is good for marine aquariums, as we’ve already said. This is mostly attributable to the substrate’s substance. So, what is Fluorite comprised of, you may wonder? 

The Seachem Flourite is made of Clay gravel with pores. This means that this is different from sand or soil substrates. However, the gravels are broken down into small bits for a sand-like consistency. 

The coal is an extremely light and porous material. As a consequence, it’s perfect for aquariums with live plants. Flourite is also suitable for both marine and freshwater aquariums.

On the other hand, Eco-Friendly substrate is made of Soil made of volcanic basalt. Since the material is a bit unfamiliar, people often ask, what is Eco-Friendly made of? Does Eco-Friendly contain iron?

Thirty distinct trace elements make up the volcanic basalt salt. The substance is a combination of magnesium, zinc, iron, and other elements. As a result, it’s reasonable to claim that it’s suitable for the majority of freshwater tanks.

Eco-Friendly, like Flourite, is great for freshwater tanks. Eco, on the other hand, adjusts the tank’s hue more effectively than Flourite.

When compared to the EC, however, Flourite gets somewhat cloudier in the tank. Furthermore, unlike Flourite, the Eco-complete does not need re-cleaning. Otherwise, the helpful bacteria will be washed away. As a result, you can simply open the bag and pour the Eco substrate into your tank.

You may now use Clarity to swiftly transition away from Flourite’s clarifying approach. This clarifier has shown to be dependable and efficient for me. It’s suitable for freshwater as well as marine tank water.

In the process, I’ve tested a few additional water conditioners. They’re –

Eco-Friendly is the winner.


The fish in your tank need to be able to see the surface of the water. If the surface isn’t up to par, it will have a negative impact on your aquarium. Let’s talk about the surface that Flourite and Eco-Friendly create. That will assist you in deciding what you need!

Fluorite has a Surface that is porous due to the presence of clay in the substrate. Plants may better absorb nutrients thanks to the deeper pores. Furthermore, the roots expand out and grow in a healthy manner.

The substance might, however, leak out at the bottom. This will keep the pebbles from moving apart and keep the material tight. 

Eco-Friendly, on the other hand, is made of volcanic basalt salt. As a consequence, it has a high permeability. It may extend out farther since it is porous. When compared to other substrates, Eco-Friendly may give four times the surface area. However, you must utilize it with caution.

Eco-complete, on the other hand, is easier to plant but more difficult to keep the plants alive. Flourite, on the other hand, is heavier and will hold the plants in. Smaller plants, such as glosso and HC, are more difficult to grow in Flourite.

Here’s a video that will teach you the five most important things to know about substrates for planted aquariums. These details made it simple and fast for me to plant in my aquarium.

Type of Plant and Nutrition 


https://www.petmountain.com/ is a good place to start.

Substrates aid in the development of your plants. Knowing what kind of plants work well with your substrate, on the other hand, is a smart idea. Check out the specifics about Flourite and Eco-Friendly to make an informed decision-

Fluorite clay contains a lot of minerals. If you pick the correct plants, you can maintain your plants healthy. The substrate has a lot of pores due to the lightness of the gravel.

Fluorite is the way to go if your plants require a robust root system foundation. Flourite as a substrate will benefit most plants with strong root systems. If you’re having trouble growing plants like java moss, here is the solution.

When it comes to producing rooted stem plants like ludwiga repens, ambulia, and rotala indica, however, several users discovered that fluorite isn’t as beneficial as Eco.

So, if you’ve already had Flourite as a substrate, you may use fertilizer to help your plants grow faster. The following are some of the fertilizers that I used and appreciated. Please have a look-

  • Thrive Planted Aquarium Fertilizer provides micro & macro nutrient rich food for aquatic plants, highly concentrated for 2500 Gallons of water and comes with handy pump bottle

Eco-Friendly is a nutrient-dense substrate. It’s also entirely natural, with no artificial or synthetic components. As a result, it is an excellent source of nutrients for most plants. 

It’s a thick, porous substrate with the presence of minerals and the soli. As a consequence, both fish and burrowing fish like this kind of habitat. Choose eco-complete if you have plants that need nutrients but can’t reach deeper levels.

Eco-Friendly is the winner.

pH Consistency 

A pH imbalance is the worst thing you can do to your tank. Your tank will be damaged whether the pH is too high or too low. As a result, maintaining the proper pH balance is critical at all times. 

The pH of the substrate may be influenced by it. Let’s talk about how Flourite and Eco-Friendly affect the pH of your tank. 

Flourite’s components do not emit any chemicals into the tank. As a consequence, the pH of the solution stays constant. The quality of the material is one of the key factors for the stable pH. The clay maintains the material’s integrity. As a result, no chemicals are allowed to escape.

You may enjoy the look as well as the lower pH. In such instance, combine a little quantity of broken coral with the substrate in freshwater.

Eco-Friendly, on the other hand, is composed of a soil-based substance. So, does Eco-Friendly affect pH levels?

Your pH may be affected by the Eco-complete substrate. The substance is somewhat acidic, and chemicals are leached into the water. As a consequence, after a few days of putting it up, you’ll notice a dip in your pH. If you have a problem with a high pH, this might be helpful.

However, if your pH is 7.0 or below, it might be dangerous. So, before you buy Eco-Friendly as a substrate, check your pH. 

If you’re using Eco Compelete, you may use Tetra Correct Ph 7.0 tablets to balance the pH of your water. These pills will assist in maintaining a neutral pH and reducing stress in fish.

Flourite is the winner.


If you like keeping aquariums, money may not be a major concern for you. However, for many individuals, the cost of materials is a significant factor. It’s also difficult to discover anything that delivers both quality and a reasonable price.

As a result, price is an important consideration. When it comes to the argument between Flourite Black Sand and Eco-Friendly,

If you can’t decide between Seachem Flourite Black and Eco-Friendly, go with Seachem Flourite Black. Knowing the price might be beneficial. 

Fluorite is the most costly of the two when compared to Eco-Friendly. It costs roughly $32 and is only available in 15.4 pound sacks. Eco-Friendly, on the other hand, is a more cost-effective choice. As a result, the Eco-Friendly vs. Flourite Black argument already has a winner.

Eco-Friendly goods come in 20-pound packages. You may purchase them for as little as $22 depending on the source. As a result, if you’re searching for a low-cost option, Eco-Friendly is ideal!

Eco-Friendly is the winner.
