I remember my first real 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 quick 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 loud mountain of Ohko stone Id piled in the center. Thats the day 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 approximately their fish.

Lets be genuine for a second. Math is boring. afterward you bring house a further tank, you want to see the scaping, the buoyant shimmer, and the fish swimming. You don't want to sit there taking into account a calculator and a conversion chart bothersome to figure out if your Aquarium Size is actually what the sticker on the box says. Spoiler alert: It all but never is. Most manufacturers find the money for you the gross volume based on outside dimensions. They don't account for the trim. They don't account for the water parentage creature an inch from the top.
