[Dewey]

I got a few corals with a aquarium i bought from another guy.Heres what i got. I think i identified theses out of a book.

1-calasterea (
1-capanella is attached to a piece of live rock.
2- helmidia . Green leafy plant

imo new to corals do i need to give them calcium? If so how often ? and what brand do i get? Thanks Duane 8)

the last is an algae not a coral so all you really need to do for is is provide light and decent water quality.

Corals overall wont need a calcium supplment if you do regular water changes and your calcium load is light. If you have just a few corals in your tank then it could be your calcium level is light enough not to need much suplmentation of calcium or other trace element levels.

How large is your tank?
