Argamilk and the like are additives for alk
and are not used by soft corals. Unless you have scleractinians (hard corals) I would stick with regular water changes. If you ever do end up with scleractinians, I would not opt for the Argamilk either. Quite messy and not very effective. A two part balanced additive or kalkwasser would be much better for a demand that water changes could not keep up with.
As with any crab, they are oportunists. Although touted as reef safe
, mithrax can be a concern so keep an eye on it.
