Thanks! My tank is only softies and lps so I point most of the flow at the surface for more gas exchange. I moved my disco to a really low flow (basically nonexistent flow) & it's reattaching to the aquascape. First to bail out of my rhicordia & rhodactis so I'm hoping the others are a bit more tolerant hahaIt actually disappeared a few days later. Hate to say it, but pretty sure one of my many CuC took it and I won't be seeing it again. That or the current got to it in that container somehow and it is stuck in the rocks or filtration system somewhere. Either way haven't seen it in weeks unfortunately.
I did learn a valuable lession though and actually relocated ALL of my Discosomas to lowest flow, low light areas of the tank and they are growing and spreading like crazy.
