that was in 8/10. It probably grew another 1-2" around since then. They encrust forever and then shoot up. I've noticed it branches off more every time I cut it..
I think high flow is the key with this one. I had it in medium flow for about 6 months and it didn't do a whole heck of a lot maybe just encrusted a little. About 2 months ago I moved it to a really high flow section of my tank and the polyp extension is incredible and it has tripled in size.
