I yet remember the sound. It wasn't a snap or a bang. It was a slow, agonizing groan coming from the floorboards of my third-floor apartment. I had just curtains scaping a sweet 55-gallon long. It was my narcissism and joy. Id spent three months salary on imported Ohko rock and high-grade ADA Amazonia soil. I felt subsequently a king. That is, until I realized my "king" setup weighed as much as a baby elephant. I hadnt used an aquarium size calculator weight calculator assist then. I just assumed "Its lonely water, right?" Wrong. categorically wrong.

When you get into this hobby, you think about fish. You think practically plants. You think not quite the perfect CO2 levels. You rarely think more or less the structural integrity of your joists. But if you ignore the math, gravity will eventually introduce itself to you in the most costly exaggeration possible. If you want to avoid a literal indoor swimming pool in your flourishing room, you obsession to understand how to calculate the full weight of your setup aquarium. Its not just very nearly the glass and the liquid. It's the total of its parts. And those parts are heavy.

Lets be honest. We every eyeball things. We see at a 20-gallon tank and think, "I can carry that." Sure, empty, its a breeze. But water is a dense, unforgiving mistress. One gallon of buoyant water weighs roughly speaking 8.34 pounds. Saltwater?
