Gents just thought I would share. I e-mailed them asking to buy a 25kg bag and this was the reply:
Good morning Eric,
We no longer supply Olsen’s Green Bio as this product has been taken off the market. Here are the contact details for the closest substitute:

The website is the supplier for Bactivate so it seems that is the replacement for Green Bio.
