You're right of course Clive. Forgot to change that bit. Nothing's perfect but we'll keep trying.

Exactly right LivanEscudero. Thanks for that. I spent hours and got nowhere.
I'm amazed that it's only in AU and NZ but it's sure common around here.

Thanks Gerardo yeah we have big kelps here. So maybe it's float bladders from kelp.
