100% chlorine tablets

[El curato]

Hi Elgin I already use sodium hypochlorite 14%, what I am looking for is cal hypo tablets which do not contain any stabiliser.

What!  100% chlorine is a poisonous gas.  It will KILL you!

If you want something with no stabiliser in it then try Sodium Hypochlorite.  You can get it in Mercadona as it is basic bleach.  The one in the yellow bottle has no additives so is the best to use.  That said it is only 5% concentration so you will need a lot of it.  Longos used to sell 10 or 20 litre bottles of 15% concentration but I haven't seen it in a while but you should be able to get it from elsewhere.  Most pool shops don't sell it because it is cheap and they want to sell their over priced stuff.

Does anyone know where sell pure chlorine tablets, not trychloror or dicholor etc which contain stabiliser. Looking specifically for tablets not liquid if any one can help?

Thanks for reading
