I like thought I had a "true" 20-gallon long. I treated it in the manner of a 20-gallon. My nature melted within forty-eight hours. Why? Because I didnt know how pull off I cleverly calculate the volume of my aquarium gallon size calculator in cubic inches. I forgot that glass has thickness. I forgot that substrate takes taking place space. I was basically guessing. Don't be with me.

Calculating aquarium volume is the first performance of fishkeeping. It is the introduction of everything. It dictates your filtration system requirements.
