Yes, I am still trying to take in all the specifics and keep them straight.
I have a huge amount of Chaeto but small tanks and no refugium, but I would like one for my 12G, the small tank I do have will not fit in the cabinet. Was thinking of making custom sized tank sometime. After seeing Bubbas Jig set up seems possible. Plants are such good cleaners, and sands are good filters too (As in nature, truly amazing really. Have you seen the Biodome with sewerwater turned back into potable water after the plants clean it?).
I have a premade acrylic HOB one which came with some stuff I bought or traded for but have never used it. (Don't really know what I am doing yet!) If you do a set up for one make sure to let me know so I can follow along and learn.
