Ann: Half Yearly Report and Accounts , page-7

As I recall it was 38 days. The culprit was later identified as excessive bacteria due to the tanks not being properly dried out and cleaned from the previous year's (kingfish?) program.

Now we have a dedicated facility, an enthusisastic team that will do whatever it takes, and professional management to guide them in the right direction.

Hold on to your hats!
