Calculate aquarium substrate volume and optional mass.
Adjust parameters in the left console to initiate real-time telemetry and biological safety verification.
2.0 to 2.5 inches average depth providing robust root anchorage without anaerobic stagnation
> 4 inches fine sand without burrowing organisms (causes toxic hydrogen sulfide pockets)
Stir deep fine sand monthly or introduce Malaysian Trumpet Snails to continuously aerate root zones.
Account for 10–15% water volume reduction when calculating livestock stocking density.
Never aggressively gravel-vacuum soft baked clay aqua-soils; siphon only surface detritus lightly.
Calculate the estimated volume of substrate needed for your aquarium from its footprint and substrate depth. A front-to-back slope is represented using the average of the supplied front and back depths.
Optional mass: substrate density must be supplied by you. Substrates vary in density, so this calculator does not assume a universal density or weight per gallon.
