Today I started a 1800g tank for my butterfly koi, sounds crazy I know but I just love them so much that I want to see them all the time. This is the start of the tank, All the wood used in this project is going to be what I've had for yr's from building my house. I could use some help on what to use to seal the tank with, I was told to use epoxy. also how do you get a seal between the glass and tank? I dont have a clue can someone please help me!
