I vividly remember the first era I set up 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 pleasing river stones. I thought, Yeah, this looks roughly right. It wasn't. It in fact wasn't. By the era I got home and rinsed the dust out, I had barely covered the glass. It looked bearing in mind a desolate moonscape, not the lush Amazonian paradise I had promised my progressive tetras. past then, Ive realized that guessing is for losersor at least for people who like making three trips to the accrual in one afternoon. You need an aquarium size calculator substrate calculator that actually accounts for reality, not just some distracted "rule of thumb" scribbled upon a napkin.

Lets acquire real for a second. Most people will say you the conventional "one pound of gravel per gallon" rule. Im here to tell you that declare is essentially garbage. Why? Because a 20-gallon "long" tank has a no question exchange footprint than a 20-gallon "high" tank. Volume doesn't breathing upon the floor; surface place does. If you want to know what amount of gravel realize you actually need, you have to end thinking virtually gallons and start thinking practically square inches and height goals. Its basic geometry, even if we every hated math in tall school.
