I vividly remember the first get older I set going on a 55-gallon tank. I walked into the local pet store, full of hubris and a slightly too-large coffee. I grabbed three bags of all right river stones. I thought, Yeah, this looks about right. It wasn't. It in fact wasn't. By the times I got house and rinsed the dust out, I had barely covered the glass. It looked as soon as a desolate moonscape, not the lush Amazonian paradise I had promised my cutting edge tetras. since then, Ive realized that guessing is for losersor at least for people who later than making three trips to the gathering in one afternoon. You need an aquarium substrate calculator that actually accounts for reality, not just some preoccupied "rule of thumb" scribbled on a napkin.

Lets get real for a second. Most people will tell you the satisfactory "one pound of gravel per gallon" rule. Im here to tell you that announce is essentially garbage. Why? Because a 20-gallon "long" tank has a extremely alternating footprint than a 20-gallon "high" fish tank sizing. Volume doesn't rouse on the floor; surface place does. If you desire to know what amount of gravel get you actually need, you have to stop thinking roughly gallons and begin thinking approximately square inches and intensity goals. Its basic geometry, even if we every hated math in high school.
