Aloha don, I'm in the middle of setup. I have a 50 gal tank, a 20 gal tank, some totes from lowes to use as gb. I was considering setting up a raft of sorts, cups or a basket sitting in a pvc return pipe to the ft. I'd like to cycle the water to the 20 gal tank from the 50 gal ft to use it as the filter tank, then pump from there to the top go and let gravity take care of the rest. As far as seeds I am looking for a good source, somewhere to get heirloom seeds from to get started.
