The ceiling height will be 10 feet... I did think of a catwalk kinda deal but that was nixed by the s/o.
One of the things that I haven't figured out yet is how to manage the lighting fixtures when I need to do maintenance. I have three 400 Watt Hamilton Cozumel Sun Pendants that will be inter-spaced with three Kessil A360X LEDs supplemental lights that I want to hang 12 inches off the water. I feel like those Cozumels will get HOT and I don't want to burn myself bumbling around in the tank. I'm not sure I completely understand your description of the "folding catwalk" system? That may be an easier sell...
For flow I think I'm leaning towards Tunze Masterstream 6550s for the form factor of the nozzle protruding more... my idea is to have them behind an in-tank divider so that they're hidden. I'm working on some sketches to show what I mean.
Thanks for the input!
Have you thought about hiding the PH in the rockwork? I saw a video on YouTube a few months back of a maintenance company that built a 300g DT with massive amounts of rock, and hidden in the rock were MP60s. If the guy didn't point them out, you'd never see them, and the tank had tons of flow throughout
