How much sand or water do I need for a portable hoop base?

Fill the base completely for maximum stability. Sand is heavier than water (about 13 lbs per gallon vs 8 lbs per gallon) so it provides more stability. A 35-gallon base filled with sand weighs about 455 lbs. The downside of sand is that it makes the system nearly impossible to move. Use water if you need to relocate periodically.

Can I dunk on a portable basketball hoop?

Only on heavy-duty portable hoops with breakaway rims and 40+ gallon bases. Light-duty hoops will tip over or break during dunks. Never hang on the rim of any portable hoop for extended time. For regular dunking, an in-ground hoop with a pro-style breakaway rim is the only truly safe option.
