Nate, I noticed in your photo gallery you were mocking up some overflow boxes. If you do not consider it unethical, look at the glass-holes.com site. They have engineered and hydro flow tested overflow boxes with different dimensions and different bulkhead sizes for different flow rates. Their notches are all 1/4" wide so easily made with a router. They show dimensions and bulkhead sizes for each of their designs. The adventure is a private venture owned and operated by a mechanical engineer who is a reef keeper. He answers emails 7 days a week and even worked on a three piece custom job for me over the holidays and did excellent and reasonably priced work. Your doing great work but your box seems over sized for a 65 gallon tank, unless you want to use a 2" bulkhead. Thats over 1200 gallons per hour potential. I double up my overflow potential though (I believe in redundancy). I use an overflow rated at 2500-3500 gallons per hour for my 120 gallon tank, but only flow 1100-12000 gph through it, as I have only a 40 gallon sump. I make up my other circulation with external circulation pumps in dedicated circuits. It is nice to see someone going straight to through the wall overflows instead of fooling around with over the wall units.
