I am getting ready to put some bulkheads in place of my DIY overflows.
It not that the overflows don’t work, they have worked fine for over 3 years. Its just that I need to reposition the that then main tank and need the extra bit of room and the the “SALT CREEP” is start to really bother me.
I ordered 2 “Standard Threaded Bulkhead Fitting - 1-1/2in” from Marine Depot and I ordered a 60mm Diamond hole saw from e-bay.
One of the bulkheads is going from the refugium to the main tank and the other is going from the main tank to the smup.
All of the parts should be here in a week!
