Changes

Below is the draw up of the build out for this prop up tank. As you can see it uses quick disconnects but you can use tri-clover connects as well. It also uses a diffusion stone that connects into one of the ferrules allowing you to trickle in gases. The picture shows a diffusion stone directly into the fermenter but its since been adapted as shown in the other pictures below to allow the diffusion stone to be behind a valve so its only exposed when needed. It also uses a whirlpool connector that goes into the fermenter creating the whirlpool when the pump is on.
