OK, I have decided to go in a different direction than the nori. I found a website that sells dulse seaweed. I have heard mention on ReefCentral of people feeding this to their tangs. It is sun dried only - no further processing. I am going to order some and give it a try.

Cost:
1-3 Lbs - $12.50 per Lb.
4-9 Lbs - $11.50 per Lb.
10-19 Lbs - $10.25 per Lb.

If you would like to give it a try, I could add to the order. Would like to have it placed by the end of this week. I will not know shipping until the order is placed.
