well things are all good now with the anubius and I am actualy in the process of breaking the tank, that had this particular specimen in, down.Kind of consolodate things for a while as I am temporarily unable to attend my tanks for a while.I do think you were on the money though.I stuff my tanks with plants and just let things ride until I see a problem,unlike some of my reef tanks were I dose consistantly as to avoid any depletion of elements.hmmm maybe I should start some more fresh water dosing.
