I am sure this has been answered plenty in different threads, so I apologise in advance. What can safely be used to attach corals to live rock whilst the rock is still underwater & in place in the tank ?
I prefer to attach the corals to smaller pieces of live rock first, and then place them in my tank. Reason for this is that I like to requascape everynow and then and if the corals are on large pieces of rock it makes it difficult as they canthen onyl be placed in one or two positions.
Withthe corals on smaller pieces of live rock (say 1/2 palm size about) it is easier to move them around to accomodate aquascaping. The small pieces are also easy to stick in gaps in the rock.
