I vividly remember the first period I set in the works 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 usual river stones. I thought, Yeah, this looks approximately right. It wasn't. It in fact wasn't. By the mature I got house and rinsed the dust out, I had barely covered the glass. It looked in the same way as a desolate moonscape, not the lush Amazonian paradise I had promised my higher tetras. previously then, Ive realized that guessing is for losersor at least for people who past making three trips to the growth in one afternoon. You infatuation an aquarium water volume calculator substrate calculator that actually accounts for reality, not just some absentminded "rule of thumb" scribbled upon a napkin.

Lets get genuine for a second. Most people will tell you the customary "one pound of gravel per gallon" rule. Im here to tell you that regard as being is in reality garbage. Why? Because a 20-gallon "long" tank has a totally substitute footprint than a 20-gallon "high" tank. Volume doesn't enliven upon the floor; surface area does. If you desire to know what amount of gravel get you actually need, you have to stop thinking not quite gallons and start thinking just about square inches and sharpness goals. Its basic geometry, even if we all hated math in high school.
