You need to know because if you overdose your fish once copper or salt based on a guess, things go south fast. I later than thought I had a "true" 20-gallon long. I treated it with a 20-gallon. My natural world melted within forty-eight hours. Why? Because I didnt know how do I cleverly calculate the volume of my aquarium in cubic inches. I forgot that glass has thickness. I forgot that substrate takes going on space. I was basically guessing. Don't be once me.
