Aqua Natural Substrates are 100% natural, sustainably sourced, triple-washed, and kiln-dried gravels and sands designed for all aquarium types, including planted tanks. Each product is meticulously graded to provide natural beauty, easy cleaning, and a large surface area for beneficial bacteria.
Select Aqua Natural Bio-Substrates come bio-activated with live nitrifying bacteria, including patented strains of Nitrosomonas and Nitrobacter, which help convert harmful ammonia into nitrates for a healthier aquarium. These live bacteria are harmless to aquatic life and can be used alone or mixed with corresponding dry Aqua Natural substrates to support stable, well-balanced water conditions.
