I vividly recall the first grow old I set taking place 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 within acceptable limits river stones. I thought, Yeah, this looks more or less right. It wasn't. It in reality wasn't. By the period I got house and rinsed the dust out, I had barely covered the glass. It looked when a desolate moonscape, not the lush Amazonian paradise I had promised my vanguard tetras. back then, Ive realized that guessing is for losersor at least for people who in the manner of making three trips to the accretion in one afternoon. You dependence an aquarium water volume calculator substrate calculator that actually accounts for reality, not just some absentminded "rule of thumb" scribbled on a napkin.

Lets acquire genuine for a second. Most people will tell you the enjoyable "one pound of gravel per gallon" rule. Im here to say you that judge is in point of fact garbage. Why? Because a 20-gallon "long" tank has a totally every other footprint than a 20-gallon "high" tank. Volume doesn't rouse on the floor; surface area does. If you want to know what amount of gravel reach you actually need, you have to end thinking about gallons and begin thinking very nearly square inches and height goals. Its basic geometry, even if we all hated math in high school.
