These planters work pretty nice in combination with the riparium planters because both kinds of systems are well-suited to low tech & low maintenance methods.
My favorite kinds of plants to use with Tank Planters are various crypts, especially Cryptocoryne wendtii varieties, and certain sword plants, especially Echinodorus cordifolius and Amazon sword. Hardy cryps generally start to grow right away in the planters, but swords take somewhat longer to recover and begin growth after having their roots trimmed back.
