too much flow...
I keep mine down in the sand away from the rocks, it's in a moderate flow and has it's moments when it will stop and start pulsing. I keep it secluded because it can grow out of control in your aquarium. As for flow is concerned, I use a WP40, Korelia 550 and have two returns from a 9.5 Magdrive in my 75g. Also feeding the aquarium with phytoplankton tends to get it's attention as well, just my .02Hi, i am new to saltwater hobby and dont know why my Xenia is not pulsating? Had it over a month and not even once i had seen them pulsed before. All water perimeters are good, please advise?
