when is it safe to add coral into tank

depends.. post details.. parameters.. length of setup.. etc.

ultimately you're looking for stable parameters..
Alk - 9-11
Calc 400-440
pH - 7.8 - 8.4 but STABLE at some number in this range
Ammonia - 0
Nitrite - 0
Nitrate - 0
Phosphates - 0

every thing is 0 except nitrates about 10 tank havs been set up for a mounth and a half 29 gal about 20lbs live rock 15lbs live sand have two damsals and one dotty back one blue leg hermet and one emerald crab


have you ever seen little red and orange leaves growing on live rock is it some kind of macro algae????

What kind of lighting do you have? You'll need to work on the nitrates. Is this a biocube?

Does it look like this?
