Nice pics Marc. Question, on a scale 1-10, ten being very difficult, what would you rate your experience with keeping gorgonians? I am curious about them.
There are two kinds, light-loving (photosynthetic) and then the opposite (non-photosynthetic) that require food in the water often. The ones I'm keeping seem to be doing quite well, feeding off the particulates moving through the water column and basking in the 10,000K lighting from above. Some of the prettier kinds don't need light and have to have more food. It's hard to maintain good water quality with those types, so I don't keep them.
Mark, there is an easy fail safe way to avoid this overspilling if you can't get your sock inside of the sump. I just cut a small maybe 1 inch by 1 inch hole on it towards the top and then when it starts spilling out of the little hole, I know it is dirty and time to replace with a clean one =)
Great tip!
