Not much of an update, but now that my sand has settled after adding it, and raising up my CL intake, I fired up the CL again, and just wanted to show the surface agitation... I think I should be good for Oxygenation. I'll try and get another vid when the lights are on... I've only got them running 2hrs/day right now..
