Question How much gravel should i have?

I have a tank 15Lx15Wx13. Is one bag of 7kg fluorite black sand enough? How deep the sand bed should be?

You'd probably want 2 to 3 inches of substrate depth. And is this flourite gravel or flourite sand?

It's flourite black sand. And the calculator says I need 15 lbs to archive 2" deep sand bed in 15x15 tank. So I guess I have enough flourite sand for a planted tank.
