Ok, ran into my first problem. The flow from the return is blowing so hard into the front glass that it is blowing the sand straight out. Salinity is at 32. Just added more to bring it up to 35 so that is what the white stuff is in front of the sand.
Looks like I will be ordering some locline and a Y to direct the flow behind the rockwork.
