5 still the longest lasting stone I've found

heavy enough to stay @ the bottom, better than the smaller ones.

heavy, stays put. the more volume air you put through it, the better it works.

Stay sunk @ the bottom really well, expected the 2" to last a bit longer but they're priced well enough to stock'em up. The new H/V air pump may help'em last a little longer.
