This isn’t my first experience with this. This is 70 pounds. I have another 80 and 250 pounds of sand coming from the great ladies of @LiverockRocks. Man, I cannot tell you how great they are to work with. Probably some of the best communicators I have worked with during my build. In the first video below, I know it’s not an aiptasia, but I’m not sure if it is similar in nature. The life on these is insane. Far better than I have seen in the past. Please be warned I am no James Cameron. I’m doing visual inspections right now. For size reference my sump is 72”x23” and I have a couple kessils over my sump just for a little light exposure.
