I vividly remember the first period I set stirring 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 enjoyable river stones. I thought, Yeah, this looks roughly right. It wasn't. It really wasn't. By the grow old I got house and rinsed the dust out, I had barely covered the glass. It looked gone a desolate moonscape, not the lush Amazonian paradise I had promised my forward-looking tetras. in the past then, Ive realized that guessing is for losersor at least for people who similar to making three trips to the deposit in one afternoon. You obsession an aquarium calculator substrate calculator that actually accounts for reality, not just some distracted "rule of thumb" scribbled on a napkin.

Lets acquire genuine for a second. Most people will say you the pleasing "one pound of gravel per gallon" rule. Im here to say you that announce is essentially garbage. Why? Because a 20-gallon "long" tank has a enormously substitute footprint than a 20-gallon "high" tank. Volume doesn't stimulate on the floor; surface area does. If you desire to know what amount of gravel realize you actually need, you have to stop thinking just about gallons and begin thinking virtually square inches and intensity goals. Its basic geometry, even if we all hated math in tall school.
