For those of you with bare bottom reef tanks
Do you guys put your rocks directly on the glass or are they lifted off the glass? I am trying to decide whether to make argocrete rocks with "table legs" to act like platforms and then pile the rocks on the platforms or pile the rocks directly on the glass? What are the pros and cons to both?
Secondly does the bottom gets covered with various algaes and polyps in time? If so how long?
