Dear Leslie,

Bleach should always be used by itself, not mixed with any other soap,
detergent etc. Standard bleaching products like Chlorox has got around % 5
active ingredient in it and it can be used directly with most of the shells
as indicated in previous mails. However, it still works ok with many of the
shells in much lesser consantrations, so liquid bleach can be diluted for
economical reasons when used in bulk. Active chlorine directly reacts with
organic material like algae and therefore gets neutrialized. It is a good
practice to add a little more chlorine after the first reaction of bleaching
to keep the solution active.

Best regards,

Ankara,Turkey)
