ever since i evicted my xenia from my LR and started it growing on my glass (which it is, like a champ) it is not pulsing. for flow in the tank right now i'm still down to just my koralia 3 (in a 37g) since i still have my mj900 turned off (after it sucked up my nem) so there is quite a bit of water movement... BUT, it used to pulse with both pumps running when it was on the LR so i don't think it's because of the flow..? is there a reason that xenia doesn't pulse? i assume it's healthy since it's growing..? i miss seeing it pulse it's bumming me out a bit
