The Shortage of ADA Amzonia

ADA Amazonia is known as the most effective aquarium soil, especially for heavily planted aquascapes. It is very rich in nutrients and automatically adjusts the pH level to around 6.0, which is the ideal acidic level for most plants and fish. Although it requires some techniques to set up an aquascape with Amazonia due to the surplus of its nutrients, it promotes the growth of the aquatic plants vigorously.

On 4 March 2019, ADA announced that they are no longer able to retain the production of Amazonia due to the shortage of its material. ADA says they are not sure when it will be back on market. This doesn’t mean Amazonia has been discontinued, but unfortunately, it’s safe to say it will be out of stock for a while.

ADA claims Amazonia ver.2 can be used as an alternative to Amazonia. However, it is not so rich in nutrients. If you are a beginner or planning to use only low-tech plants, Amazonia ver.2 will totally be up to your liking. Even for those who are planning to plant heavily, Amazonia ver.2 is a good choice because it has solid fertiliser called Amazonia Supplement within the bag.

Introducing Rivera Soil 

I have been using Amazonia ver.2 for about two years and so far, I am satisfied with the growth of aquatic plants. But in this article, I would like to introduce aquarium soil called Rivera Soil produced by DELPHIS, a Japanese aquarium brand.

Rivera Soil is said to be as rich in nutrients as Amazonia but makes the water less cloudy at the time of the setup. The official site says the pH level will be around 6.0-6.5. It is all made in Japan.

The price in Japan is slightly lower than that of ADA Amazonia.


I would say Revera Soil is amazing. The growth of aquatic plants seems fairly faster than Amazonia ver.2. Put simply, it can be assumed the amount of nutrient in Rivera Soil is larger. However, in my tanks, aquatic plants did not grow as fast as they would do with Amazonia soil.

Another benefit I need to point out is that Rivera Soil does not make the water cloudy. Usually, it takes about a week for the water to be clear when Amazonia is used. And this requires a strong filtering system and stable water condition. Therefore, Rivera Soil is easier to use.


If you are looking for an alternative soil to ADA Amazonia, I would totally recommend this product.

Here is the link for purchasing Rivera Soil. It may cost more than its original price to ship the product abroad, but it is worth trying it out!
