Scubadawg's 187 Gallon Tank Journal - Edmonton

[scubadawg]

Thank you for your comments, I am still a newbie at reefing, I started with a 20 gallon long tank in May, I am still learning about overflows, when I design the tank and overflow, I made it so I can make changes, this is in my living room so I wanted to keep this dead silent, so is this what I will need in my main drain?
Do I need to drill and tap the pipe to put a fitting in?

All my 1.5" bulkheads are slip



Does someone in Edmonton have a Beananimal setup? that I can get some advice from? Thanks
