Just like buying a brand-new mobile phone or a car, you need to read reviews to find the best planted aquarium substrate. That is why I have created a bunch of reviews to help you select the best planted aquarium substrate.
1. ADA Aqua Soil Planted Aquarium Substrate
ADA Aqua Soil is, hands down, one of the best planted aquarium substrate options, in my book. Although there are tons of clay or volcanic soil aquarium substrates, ADA is quite unique compared to its counterparts.
It is, based on the mulch of decomposed leaf. And that means it is incredibly rich in nutrients and elements, making it an exceptional solution if you want lush growth for your aquatic plants.
Decomposed mulch is mostly known for creating small granules. But, the ADA aqua surprisingly has large pellets of soil created by soil lumps that were compacting.

So, it retains the water’s neutrality, meaning it is also safe for your fish.
The way I see it, the substrate is at its best when used on its own at the aquarium bed. Still, you may blend it with gravel so that you can make it a little more diverse.
There might be a bit of cloudiness on the water on your first use of the Flourite Black. In fact, you may have to use some mechanical filters to remove the water’s suspended particles.
You can reduce it, though, by rinsing the aquarium substrate to remove any dust that has formed when the clay crumbled as the item was still in transit.
Thankfully, once you have laid down the clay, it will not need any replacement in the fish tank’s entirety.
