Instantly find your tank's precise size in gallons or liters. Accurate volume is the first step to a thriving aquatic ecosystem.
Net volume assumes ~15% displacement for substrate and decor.
A healthy tank starts with knowing exactly how much water you have.
Medicines and conditioners are potent. Accurately knowing your volume prevents toxic overdoses or ineffective underdosing.
Your tank's biological capacity is limited by volume. Use this number to calculate stocking density and keep stress levels low.
Heaters and filters are rated by gallonage. Matching equipment to your true volume ensures efficiency and stability.
The calculator provides the Gross Volume (empty tank). However, substrate, rocks, and decorations displace water. Most aquarists subtract 10-20% to find the Net Volume (actual water).
