Feeding Algae Eaters

So I know most everyone here uses nori to feed their algae eaters their much needed veggies. However, leaving nori in the tank for extended periods adds to nutrients and other issues. I've done the leave it in for a bit and take it out, but it often turns to mush quick and escapes my collection. Or in my most recent case, my cleaner shrimp goes to it immediately and shreds the dickens out of it.



So I ordered this, http://ift.tt/198csq8 It probably isn't as good as nori or other seaweed but it is easier to control. What do you all think about this as an appropriate algae source for our algae eating fish?
