Things to Consider Before Buying

As mentioned earlier, the primary use of a substrate is to increase the growth of your aquatic plants. Choosing the best substrate makes a massive difference in your planted tank, and it can also impact the outcome of your aquarium.


Other than aquatic plants, they also maintain the health of the fishes and different marine life. The one we are reviewing today has some demerits too, and you should know it before hopping on the purchase train.

·      Not Suitable for Cories and Loaches

Cory catfishes are small and peaceful aquatic creatures who reside at the bottom of a planted tank. They are known as bottom dwellers, so they mostly live in the fertilizer.

Loaches, too, are freshwater fishes, known to live at the bottom of an aquarium. These two types of fishes might not be compatible with living together, but they are also unsafe if planted in a tank filled with Seachem Flourite.

This is because some of the pieces of the fertilizer are sharp. So, the sharp pieces might cut and injure the bottom-dwelling cories and loaches. If you happen to have any of these in your planted tank, then this substrate is not for you.

So, you can choose the color that best matches your aquarium and its environment. The fluorite stones mixed in the fertilizer are beneficial for a planted tank because they are firm enough to hold the plants in place while you set up the tank.

Furthermore, it is not coated with any harmful chemicals to ensure the safety of the planted aquarium. The substrate can also manage the pH level of your aquarium without unsettling the overall environment of it.

However, the substrate dominating the market is the ADA Aquasoil. The fertilizer is rich in nutrients, which promotes the growth of aquatic plants. It also keeps the water from being cloudy after it is ultimately settled in the planted tank.

But it produces ammonia in the soil a lot slower than the Seachem Flourite. Also, the Seachem Flourite substrate will not affect the pH level of your tank. Another alternate you may consider is the Fluval Stratum.
