I have a 65g tank plumbed into my system which is for the sole purpose of water changes. There's a bulkhead at the top of one of the side panels which drains into my sump. Water is fed to it by my manifold so when I want to do a wc, I just turn the bv off to isolate the tank. there's a mag 7 pump in the tank that pumps the water out to my slop sink and then I fill the tank back up. Once its fill I open the bv back up and new water begins to mix in with the old water gradually. I can do a 65g wc in about 20 mins and the best part is I can walk away while the water is draining and not have to worry about over draining the tank. I also have a small powerhead in there to just keep the water moving around and stir up any sediment that may reach the tank.
