I remember my first genuine aquarium disaster. It wasn't a leak, and it wasn't a cracked pane of glass. It was a math error. I had this delightful 55-gallon rimless setup. Or at least, I thought it was 55 gallons. I measured the uncovered dimensions, did some fast mental math, and started dosing my water conditioner. Two hours later, my Neon Tetras were gasping at the surface. Id overdosed the tank because I forgot to account for the thickness of the glass and the all-powerful mountain of Ohko rock Id piled in the center. Thats the daylight I realized that most hobbyists are just guessing. We are carried by the wind blind in a sea of "close enough." That is until I stumbled on the Einstapp Fish Tank Volume Calculator: The Most Accurate Resource for anyone who actually gives a damn about their fish.

Lets be genuine for a second. Math is boring. as soon as you bring house a further tank, you desire to see the scaping, the vivacious shimmer, and the fish swimming. You don't want to sit there behind a calculator and a conversion chart trying to figure out if your Aquarium Size is actually what the sticker upon the bin says. Spoiler alert: It in relation to never is. Most manufacturers have enough money you the gross volume based upon uncovered dimensions. They don't account for the trim. They don't account for the water descent being an inch from the top.
