How much sand should I use?

[BrknWrldsWthin]

I'm looking at using black diamond blasting sand on a new 75 gallon tank. Tractor Supply sells 50 lb. bags -- I was wondering whether I should go with 100 lbs. or 150 lbs.? I haven't used sand in a tank before. Thanks.

You should be good with 100lbs

Yeah, 100 should be plenty. Just be prepared to do tons of washing.
