i'm settin up a 90 with pretty much the same dimensions as a 75 just a bit higher but i figured theres more 75's here then 90 so lets see them,i'm looking for decorrating ideas,
The cheapest pebbles I could find. They are small and smooth(kind of like river rocks). I got 50 lbs bags for $1.50. Very dirty stuff, but I'll take some time and wash my rocks to save some money.
