Thanks Mandarinman, I am rather going to give a skip on the iodine situation until I have a better understanding and knowledge of ther more important aspects of mairine tanks and the ongoing around them. I am still learning to get things right with the tanks and if I go past go, don't collect $200 and go straight into the other aspects of coral care and so on, all I am going to get is a world of trouble in my tank by lack of understanding and knowledge. I am busy resting my tank from thowing it in a washing machine of livestock and filtration setups, big newbie mistake on my part but recovery from that is taking place - I simply can't afford to get in too deep into things right away, baby steps need to happen before I just run with this lot. As a newbie, the is an information overload and before long, it starts becoming mind blowing and one can't keep up with all the new info.
Your feedback and links is however appreciated becasue I can then take the info and begin learning those aspects, when I feel I am ready to delve into that side of things then I can go for it, but for now, I am not ready by a long ways.
