Aqua Natural Gravel REDFLINT020 Editorial Review
The AquaNatural Red Flint 20lb Gravel Substrate has received mixed reviews from customers. One customer mentioned that the gravel is perfect for their aquarium, as it is not too large and doesn't have sharp edges, and their fish love it. Another user mentioned that it works well with plants when there is a layer of soil beneath it. However, one customer had a negative experience, stating that despite rinsing the gravel thoroughly, it caused cloudiness in their tanks for several weeks, and replacing it with another type of gravel resolved the issue. **
