if you put enough on it, the aptasia x, which i hear is nothing more than kalkwasser paste, will work fine. i injected an aptasia with vinegar before and the next day there were 4 of them in the place of that one. i never tried the lemon juice.
if this is going to be a FOWLR
tank, you don't even have to worry about the majano. it can do no harm to fish or inverts. the trouble with them is they spread quickly and can sting neighboring corals.
