I have unleashed my windows paint skills on this one!
I have a 48" tank
Lighting is 2 Kessil LED
I am going to drill a Bean Animal Overflow.
My overflow box is 4" (deep) x 10" (high) x 12" (long)
The 12" side has slots in it for water flow. The 4" pieces on the side are solid acrylic - no water passes through the sides.
These are the three setups I am contemplating.
1. Overflow in the corner with 1 return line at the far end.
2. Overflow in the middle with 1 return at the end
3. Overflow in the middle with 1 return on the left side and 1 return on the right side.
From my understand all of these should be fine as long as circulation WITHIN the tank is good.
I planned to go with option 1, but if there is a good reason to do something different I'm all ears.
