LANDEN Aqua is significantly less expensive than UNS, Tropica, ADA Amazonia, etc. LANDEN Aqua added it to a plant grow out tank and put fish in the same day, using a sponge filter that was fully cycled and mature. They didn't see any ammonia spikes, fish stress, or deaths. Plants are developing great. One of the best substrates for Dwarf Shrimp hobbyists is Aquasoil Amazonia. It contributes to keeping the water soft and maintaining a pH that is slightly acidic. Aquasoil Amazonia has one major drawback, however: when new, it causes a significant spike in ammonia. The color, texture, and grain size of CaribSea EcoComplete and ADA Aquasoil are perfect. They provide fish and plants with perfect water chemistry and high levels of nutrients. They can lose nutrients and texture over time, with some varieties breaking down into mush. They ought to be changed once per year.
