Natural sea water vs instant sea water

I live close to the ocean. Is there any problems if I
go ahead and get ocean water VS purchasing sea salt and do my mix. How
about water changes. Can I use ocean water? How about sand and rocks
from the ocean?

Yes, you can use stuff straight from the sea. The main problem you will have is
the possibility of pollution if you take your water from close to shore. Don't
introduce too much of the sand and rocks at any one time. They may be harboring
various little critters. If these then die in the tank, the water quality may
become so poor that your other livestock dies. This is why people "season" live
rock and sand.
