Re: Halimeda As far as I know, no they won't at least not on the larger scale that some of the other macro's will. From my understanding depending on how much you have and the other types of corals you have you might actually start having a problem with it using to much calcium or alk. Right now I am using it in mine to judge the levels of calcium and alk, as long as it is growing decent then I feel that the level those elements are at are good. |
