Do not worry. In most cases, darkening of the solution and crystals do not influence the developing capacity. Dab a bit of the concentrate on a piece of unexposed film.The film will become black in some seconds, if your Rodinal is healthy.
You can filter your developer through cotton wool. Put some cotton wool into a funnel and pour the Rodinal through it.
