Questions about your return. If you could explain this to me (new to SW since Aug '17).
Planning a new 120g drilled DT 72 x 18d x 20h to replace the current undrilled 48 x 12d x 20h (hob overflow to sump).
Double-side viewing like yours (a divider between dining room & living room)
In your first tank, and this one, there seems to be two holes for the return. On the same side of the overflow.
The first tank looked like a loop in front of the overflow, but I couldn't see where the filtered water was going. I would think you want to pump fresh away from the overflow drain. So wondering why?
On your current, there's two holes for the return to either side of the middle overflow. I can't see where the fresh filtered water is being sent. Would like to.
I get making two holes for the return - a regular (silenced) and an emergency.
Since I'm having the holes made (guy charges 20$ per hole) I thought one input - to the upper right or left, would be sufficient.
Is it worthwhile getting a total of 4 holes made, instead of 3?
Thanks. Awesome setup, wish I had your budget! Also surprised you went acrylic versus glass - I've read lots of pros & cons - I always thought that being able to repair scratches on acrylic a big plus, and no silicone joints makes it so much nicer.
