I'm going to be adding a second 2k gyre to my standard 75 gallon with overflow/return on the back left corner. I currently have the 1st gyre on the upper right side and was planning on putting the second on the upper left side? Right now I use a sine wave for flow. I was thinking of leaving it as the sine wave and using the alternating power for them? I just have softies and LPS so I'm not needing a hurricane in there for flow. Thank you for the help/advice!
