Every once in a while I check MFK for Diy Tank builds,  I have read your  entire 1500 gallon build.  I read that build  for about an hour a day, I  read it in two days. I just want to say, that tank was awesome, and was  one of the sources that helped me get info to build my 450 gallon tank.  Anyway, we are moving, and that aquarium won't fit out the doors, so I  decided I was going to build another aquarium to replace it, bigger  obviously. I drew up plans and calculated the cost and supplies needed. I  then remembered to look on here to motivate me to make sure to build  it.  The funny thing is, I just found this thread, and the aquarium you  are building now, and the aquarium I  have planned out, are very similar  sizes.  I have a square room in the house we are going to move into,  and its not long enough in length to put a big aquarium, so I am making  it in a U shape with three 8' x 3'  viewing windows. Before I ever  looked at this thread, I calculated it out to be 2,755 Gallons.  I hope to start work late fall, early winter, whenever I prep the room.  But I just wanted to say, your original 1500 gallon build is what got me into making aquariums! I hope you get your leaks figured out, and I hope you don't mind me messaging you on tips when I start my build. Thanks! and keep it up!
