Throughout the course of the study, a set of six material collectors made of natural andesite slate ( 15×15 cm) was set up in the slopeward of each station. The settling collector is placed between the reef shelf and the edge of the reef ecosystem, installed at ca. 30 cm above the sediment. The first sampling was conducted 3 weeks after submersion in the water and collectors were sampled twice a week for three weeks thereafter.
Samples of planulae were taken by scraping an area of 5×5 cm from the slate into a wide-mouth bottle. Under the aseptic condition, samples were then separated for periphyton analyses, i.e., fixed with Lugol. The bacterial samples were carried out by scraping the outer surfaces of the slate randomly in an area of 1 cm2, and put into a polyethylene plastic bag (Whirpak Nasco, USA). Both samples were labelled and kept in the cool box for further processing as soon as possible.
