If you want root feeders on there your best bet is to strip the tank down and add a layer of soil below the sand.... That will gove them nutrients aswell as gove them somethimg to hold on to... But be sure to add the sand back or the dort will make ur watter cloudy n like any movement will send a cloud of "smoke" into the column n gunk up ur filters. Jus a thin layer of soil then ur regular sand. I wish i did that but its a lil to far to turn back now...
