So far just running the 2 gyres. I have plans to eventually add 2 Octo pulse to the back walls. Right now the gyres seem to blow the sand and fish around at 70% alternating gyre mode.Are you only running the 2 gyres? I have the exact same tank (with bracing) and find my 2 Neros and 1 Gyre are barely enough.
Build looks great so far! Following along.
