So I have always had a hard time w/ water flow. I understand that for an sps tank high flow and and wave action is a must and most lps like lower flow. What I'm not getting is how to place my power heads to get the best out of them. Though I have more than enough GPH for the set up I still get build up and dead spots. I am wanting this thread to cover all aspects of this subject, so bring on the info and experience. Also please if you need info from me to help me it's here, just need to know what info out side of flow is needed. Currently this tank has 79x water volume.
