I did! Previously i put the eheim compact 600 there. And it sucked a clown fish there and it died. Was so sad so i took it out. But of course i didn't set the powerhead to it's max which is 600. But still my clown got sucked there. Horrible stuff, so i removed it and that's the result why i didn't wanna get another power head to place in the tank as it might suck my fishes there. I don't know what else i can do so i thought a wave maker might not suck anything in. Prolly im wrong? lol.
