Amazonia is the gold standard of freshwater substrates, recommended and used by the team at Aqua Lab. Rich in organic acids and nutrients, it will promote the growth of aquatic plants for the lifetime of the aquarium.
• Designed to provide a suitable environment for even the most difficult plants.
• Helps maintain a steady pH level ideal for most aquatic plants and tropical freshwater fish.
• Gives clarity to the water.
• Contains nutrients that encourage fast development of healthy root systems (be careful - a large amount of Amazonia can cause ammonia spikes).
• Helps to reduce the hardness of the water, making it easier for plants and fish to thrive.
• Amazonia LIGHT has a slightly lighter color and contains less nutrients, making it a better option for established aquariums that do not need acycling jump-start.
Amazonia soil is rich with nutrients, which can cause a spike in ammonia when first introduced into an aquarium. If you are setting up a new tank, this is useful for starting the nitrogen cycle to develop a strong biofilter. If your tank is already established, proceed with caution. Either way, be prepared to dilute with several water changes after adding Amazonia and TEST FREQUENTLY!
It is only anecdotal but I feel like the regular ADA Amazonia grew plants better. To be fair it was in a non co2 tank but if you can deal with the initial ammonia blast I would stick with ADA original.
