I vividly recall the first grow old 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 gratifying river stones. I thought, Yeah, this looks approximately right. It wasn't. It really wasn't. By the times I got house and rinsed the dust out, I had barely covered the glass. It looked following a desolate moonscape, not the lush Amazonian paradise I had promised my innovative tetras. since then, Ive realized that guessing is for losersor at least for people who later than making three trips to the deposit in one afternoon. You infatuation an aquarium gallon calculator substrate calculator that actually accounts for reality, not just some distant "rule of thumb" scribbled upon 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 say you that find is truly garbage. Why? Because a 20-gallon "long" tank has a very interchange footprint than a 20-gallon "high" tank. Volume doesn't rouse upon the floor; surface area does. If you want to know what amount of gravel attain you actually need, you have to stop thinking approximately gallons and begin thinking about square inches and height goals. Its basic geometry, even if we all hated math in high school.
