Aquarium Calculators
Plan every aspect of your aquarium setup with mathematical precision. Our calculators help you balance biological loads, evaluate heating demands, compute substrate volumes, and verify glass structural safety.
Stocking & Bioload Calculator
Our flagship algorithmic stocking calculator. Plan your fish roster, check water parameter overlap, determine layer distribution compatibility, and calculate cumulative bioload index limits.
Aquarium Volume Calculator
Find the exact water capacity of your tank in gallons or liters for rectangular, cylindrical, hexagonal, or bowfront shapes, accounting for glass thickness and substrate displacement.
Glass Thickness Calculator
Verify structural integrity for custom DIY aquariums. Input desired tank length, height, and safety factors to determine minimum required glass panel thickness based on hydrostatic pressure.
Heater Size Calculator
Determine the exact wattage needed to heat your aquarium. Factor in total volume and the temperature differential between desired water temperature and ambient room temperature.
Substrate Weight Calculator
Calculate exact volume and weight of sand or gravel required to achieve your target substrate bed depth. Enter tank dimensions and desired thickness to estimate pounds or kilograms.
Aquarium Weight Calculator
Determine empty and filled weights of your fish tank in pounds or kilograms. Calculate glass vs. acrylic weight, water weight, substrate bed load, and floor support limits.
