I spoke to a friend that survived cancer who eats seaweed (some of it was green Nori, not red) because of the supposed medicinal benefits.
Apparently, seaweed usually contains iodine in small amounts, possibly small enough that it might not be listed at all. Kelp contains much higher amounts of iodine.
She also told me, and this is the most interesting part for this dicussion, that Nori can cause an increase in phosphates in aquariums.
So, it sounds that it might not be such a good idea to use as a turtle food, but like anything, fed occasionally in small amounts it doesn't sound like there would be any long term detrimental effects either, as long as you maintain your tank water quality and check for phosphates. Also, keep in mind that your turtles are not marine turtles, so you may not want to feed them anything intended for salt water fish.
