Depends on the macro. Ninja astreas didn't eat a Gracilaria I was keeping. Nassarius are devout carnivores. I'm experimenting with mexican turbo snails at the moment.

there are plenty of macro algae that the hermit crabs and snails don't eat, if you can be more specific on what kind of macro. ie, I have a red algae, it's pretty tough, dragon flame or something similar, but the hermits and snails eat the fine filamentous algae off of it, but not the red algae itself. Also I believe chaeto is another that would be too tough. The brown algaes are also too tough.
Soft green algae like ulva would be eaten.

Sounds like I have just chosen the most delicious algae for my tank. I will try some red algae. I had Udotea sp. (mermaids fan), Rhipocephalus phoenix (shaving brush), and Halmida sp. I find my crabs on all of them eating them down to nubs.
I will try some hardier macro algae next time.

those are pretty tough species, what crabs do you have? If hermit crabs, then they are likely eating the soft, or dying parts of that plant, not a healthy growing plant.

That may be the issue. They are dying on their own after moving the crabs to anther tank. I guess the crabs weren't the problem (although they 'uproot' then a lot).

Thanks!
Cheers,
