In terms of pH impact, this substrate maintains a neutral to slightly acidic pH level, which is ideal for supporting various plant species, tropical fish, and shrimp. This makes it a versatile option for planted aquariums. It also excels in preserving water quality by preventing discoloration and managing organic waste, especially when combined with natural elements like driftwood.

The substrate's grain size provides a suitable environment for newborn shrimp by offering them shelter, which is a thoughtful feature for shrimp breeders. However, potential buyers should be aware that the substrate might not be the easiest to clean due to its granule form and porous nature, which can trap debris over time. As for color, the dark hue of the substrate can enhance the aesthetic of the aquarium and contrast well with green plants, though some users might prefer lighter substrates. The 4.4-pound bag is sufficient for small to medium-sized tanks, but larger aquariums may require multiple bags, which could become costly.
