i purchased a new zoa about 2 weeks ago and had it low just about in the sand in a lower flow area. It would not open after a week, I moved it higher in the tank to get it to a place with more flow and still nothing. So finally I placed it directly in front of my mp10 and sure enough it’s beginning to open. I was under the impression they preferred lower flow, is this incorrect?
