Hi was wondering how do i know when i am ready for Coral in my tank? i read when i start to see corline algae on my glass? is this a good rule of thumb? My tank is 7 weeks old, im buying the calcium testing kit tomorrow to see where my rates are at. Will post tomorrow. But what the ideal water conditions? Even for like some Zoanthids? I have a T5 light with 2 normal lights and 2 Actinic lights, at 54watts each. What would be my restrictions on LPS SPS and so forth
