Well I'm getting closer! Tank is full of freshwater, been running leak free for over a week. Still twerking a few things before I drain, move to it's final resting spot, and fill with SW.
So I needed an adjustable mount to hold 4 Neptune optical sensors, and it had to match my Synergy Reef Systems Red/White sump.
So this happened!
