Hmmmm think he's around 12-14". He seems to be loving it in their. Need to redo my air disk line to the black ones before I start adding my rays in their. Target as mentioned is superbowl weekend. All water test seems fine so far. Might put in one of my leo's after this weekend. After one Leo, then the rest will all go on after I'm completely satisfied that all is good. That's still going to be nerve racking so going to Fo transfer on a Friday night so I have the entire weekend to monitor them.
