I vividly recall the first get older 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 welcome river stones. I thought, Yeah, this looks more or less right. It wasn't. It essentially wasn't. By the era I got home and rinsed the dust out, I had barely covered the glass. It looked as soon as a desolate moonscape, not the lush Amazonian paradise I had promised my highly developed tetras. previously then, Ive realized that guessing is for losersor at least for people who taking into account making three trips to the amassing in one afternoon. You habit an aquarium dimensions 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 conventional "one pound of gravel per gallon" rule. Im here to tell you that declare is in reality garbage. Why? Because a 20-gallon "long" tank has a definitely swap footprint than a 20-gallon "high" tank. Volume doesn't stimulate upon the floor; surface place does. If you desire to know what amount of gravel reach you actually need, you have to end thinking practically gallons and start thinking approximately square inches and severity goals. Its basic geometry, even if we all hated math in tall school.
