Overflow box question.

[Crush Coral]

Going to install an Aqueon model 3 sump on my 75. Need an overflow box. Thinking of a double bulkhead design for redundant return lines using one and the other for backup. Double Utubes also for redundancy. Any thoughts on my idea?
Thanks

I have that and cant wait to upgrade in the near future. Mine is noisy no matter what I do and I am in constant fear of a power outage that will lead to a flood. If I was setting up the 75 again I would drill the holes instead of using the box.

My tank has been up for 8 years. I am worried about drilling with it being a functioning reef.

I understand that
I have a drilled 129 I am getting ready to set up and I can't wait to get it going. I have the eshoppes overflow. If I was going to keep
The overflow going I would do a life reef overflow. Check it out on YouTube. Those always restart once the pump does.
