How many pounds of sand can do u need for 150 gallon tank.

Granted, mine is a lot smaller, but for my 10g nano, I'm using about 13lbs. I don't know if it holds true, but that would mean a ratio of just under 1.5lbs per gallon. Woah, that's a lot of sand for a 150!!! Be talking about 200lbs.
Get some other opinions though... I'm certainly no expert.

jacksonpt is correct it's about 1 to 1 1/2ppg. The same for l/r.
