Hello all my question is can i use my fish tank water to water my tomatoes and pole beans and herbs? i just viewed a video on aquaponics how they are recycling water from fish tanks to hydroponic grow tables then back to the fish tanks. really amazing stuff , the main question is they are useing hydroclay pellets or little rocks as a medium not potting soil is this nitrate rich organic fish tank water ok to use in potting mix. i do bi-weekly water changes on my tanks and have been throwing it away down the drain for years, this my be a great way to go green and conserve water and store bought fertilizer. thanks all kingfatty
