What should/should not do with old sand? Can I just spread it out in the yard, or will the chemicals hurt my grass? It's about 300# according to the manual. Might as well change the sand while I'm in there when I replace the suspected cracked laterals. Existing sand is nasty gray looking, even after deep cleaning last summer. It's about 6 years old.
