Red Flint sand substrate is naturally occurring in the rivers and streams in nature. This enables familiar environments where sand is needed with your fish species that are not accustom to fast moving rivers that might include larger stones. Sand also closes the space between the particles more-so limiting the debris buildup that inevitably leads to breaking down organics over time which increases nitrates and phosphate and can lower water quality. When debris is on top of the substrate its easy to remove and less time in cleaning.
