Good work, The only thing I would change out is the piano hinge. It will eventually rust. I used Stainless Steel Euro hinges in my bow and after 5 years they are showing signs of rust.
I used the blum SS hinges is my stand, they are completly rusted after 2 years. I think you would have better luck with a brass hinge, it will not rust the same way if you take care of it.
The back is semi open due to HOB refugium, and potential HOB Remora.
I think I need as much airflow as possible. Have 2 4" fans on either side blowing in, and 2 4" fans on top blowing up.
Lighting - 2 150w retro HQI side by side.
- 2 T5 actinic front and back top.
- 2 Blue LED Moon
