Dear Njp1990;
Could this be of any help to you:
"Hypochlorite Decomposition Tools (http://www.powellfab.com/Technical_Information/tools/sodiumhypo_decomp.asp)”
"Hypochlorite Decomposition Info (http://www.powellfab.com/Technical_Information/preview/general_info_about_sodium_hypo.asp)”
You would get a Lot if you google for “sodium hypochlorite decomposes“
Good Luck!
