Why Calculate?

Safety and ecosystem balance start with math.

Water is heavy (8.34 lbs/gal). Knowing the total weight helps you choose the right stand and placement.

An undersized heater will burn out trying to warm a large tank. Get the exact specs you need.

Medicines and fertilizers are dosed by volume. Use exact volume for fish safety.
