The next sections will discover numerous elements influencing materials choice and supply steerage on calculating the required quantity for various setups, together with planted tanks, group tanks, and species-specific aquariums.
1. Tank Dimensions
Tank dimensions play an important function in calculating the required substrate quantity. Whereas a 20-gallon tank nominally holds 20 gallons of water, tanks labeled with the identical gallon capability can have various lengths, widths, and heights. A 20-gallon “excessive” tank has a smaller footprint (size and width) and larger top in comparison with a 20-gallon “lengthy” tank. This distinction in footprint immediately impacts the substrate calculation. A bigger footprint requires a larger quantity of substrate to realize the identical depth. As an illustration, reaching a 2-inch depth in a 20-gallon lengthy tank would require significantly extra substrate than reaching the identical depth in a 20-gallon excessive tank. Precisely measuring the size and width of the tank’s base is important for calculating the required substrate quantity.
Think about two hypothetical 20-gallon tanks: Tank A measures 30 inches lengthy by 12 inches large, whereas Tank B measures 24 inches lengthy by 18 inches large. Though each maintain 20 gallons, Tank A has a smaller footprint (360 sq. inches) than Tank B (432 sq. inches). Subsequently, Tank B would require a bigger quantity of substrate to realize the identical depth as Tank A. This precept applies to all aquarium dimensions and shapes. Ignoring the footprint and relying solely on the gallon capability can result in vital errors in substrate calculations, leading to both too little or an excessive amount of substrate.
