Hydrophornia question

[daniella3d]

6" is plenty enough, even 2" is fine. As lons as a coral does not touch it for a long period of time it will be fine.

I even have the remain of one that I detached from a rock to sell it and it is only encrusted for now but it is growing in between my zoanthids and digitata and does not seem to affect them.

Mine is a very nice light fluorescent green, very striking in color.
