It looks really good! My main concern is stability. Additionally, when it goes in the tank you will want to make sure that you have space to clean the glass all of the way around.
Thanks. I was trying to knock it over on purpose by lightly hitting it. Seemed pretty stable. And that cutout its on is 24x24 so I could try to emulate the tank. Might have to angle it a little bit.
I plan on fowlr only for at least a year. My thoughts were eventually a gsp for the front rock and maybe a few mushrooms or a war coral. But I definitely am not going heavy into corals.
