OK, the overflow was installed late last night.
And now the tank is filling up and my TBS sand is in place.
Going to fill it up almost to the overflow and leave it there so the couple dabs of silicone we used to hold the left side of the overflow will have time to fully cure.
I won't have my sump for a couple weeks at least so it won't do me any good to fill it up more than that anyway.
I have a heater running and my brand new maxspect gyre pump for circulation.
There are three 2" schedule 80 bulkheads holding the overflow in place on the right side.
And behind the tank is the outer box where the water will flow to and will contain my beananimal plumbing.
I need to now trim out around that outer box so i cover the edges of the sheetrock, the void in the wall, and make sure there is no open space around it to let anything pass between the fish room and the dining room.
And all the trim around the front of the tank has to be replaced as well..
Lots and lots of work to do!!! :)
