hi all
for those who missed the webcast the other day it is one the site know.
https://www.phoslock.com.au/site/content/

i was reading something or heard something recently about them beening able to change the composition of phoslock or something like that to expand its use. has anyone else read something like that ? and can you remember where ? ie this phoslock will deal with phospahtes and this type will deal with say arsenic or a mixture of both , could be very good in polluted waters in general
