Well the update is that the tank has been up and running for many months now. I still have a little issue with the sump that has the algae scrubber in it but the tank is doing great.
Here's some shots from inside the tank.
It's a little difficult to tell but the GATF in the pics has grown an inch from one pic to the other. The first pic is most recent.
Yup, since I had to piece together two pieces of plywood I wanted to use the tongue and groove osb. I fiberglassed it so it's stiffer but it still flexes a little. Even with bracing spaced 18" apart when I step on it I can feel it flex. There's no issue with leaks because the entire tank is glassed and Wetsuited but if I was to do it again I'd think about using regular plywood.
Sorry, nothing new to report. Just getting some brown algae on the bottom. Maybe due to feeding more or algae scrubber not doing the job. I may get a Flagtail to see if it will clean up some of the algae.
