I was searching for info about fish urea as I have two aquaponic tanks of the IBC Tote ‘chop & flip’ variety which by the way seem to be doing well, and just read your Fish Gills: 101 article.

It was most interesting, especially about the flow of fluids in opposite directions. So I learned something unexpected!

Thank you!
