Running a test in the 46 gallon bow front under gravel filter tank with plants to prove that plants in a UGF and deep substrate (4" Pea Gravel) will grow I don't vacuum the substrate and only run air power to the 1 uplift tube so that I can determine if plants will grow using a UGF. November 4th will be 2 years with this filtration my hopes are to put to rest a myth that plants and UGF won't work.
