I vividly recall the first become 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 up to standard river stones. I thought, Yeah, this looks virtually right. It wasn't. It in reality wasn't. By the grow old I got home and rinsed the dust out, I had barely covered the glass. It looked subsequent to a desolate moonscape, not the lush Amazonian paradise I had promised my far along tetras. previously then, Ive realized that guessing is for losersor at least for people who following making three trips to the addition in one afternoon. You compulsion an aquarium volume calculator substrate calculator that actually accounts for reality, not just some vague "rule of thumb" scribbled upon a napkin.

Lets acquire real for a second. Most people will tell you the standard "one pound of gravel per gallon" rule. Im here to say you that pronounce is in reality garbage. Why? Because a 20-gallon "long" tank has a unconditionally exchange footprint than a 20-gallon "high" tank. Volume doesn't sentient on the floor; surface place does. If you desire to know what amount of gravel attain you actually need, you have to stop thinking nearly gallons and start thinking virtually square inches and extremity goals. Its basic geometry, even if we all hated math in tall school.
