My friend just gave me a small colony of button polyps. I placed them in the middle of my tank (fully cycled now). I understand that they need turbulent or surge like water flow. What I want to know is what quantifies as low to medium water flow and how would I orient my power head to achieve the turbulent type of water flow?
Do the polyps have to actually sway back and forth in order to have low to medium water flow? I know there is current but the polyps don't sway back and forth.
Thanks.
