I got a couple Haddoni nems that I’ll put in my 470g reef. I’ve got two different areas to place each one and they’re both sandy areas. My flow is significant and if I let the nem free the current will take it directly to the powerheads. I’m looking for some pointers on getting them to settle where I want them. I’m think I’ll need to turn my powerheads off for a few hours? More?
Also, would it help to block them in with some liverock?
