API Tap Water Filter

[gmanova]

Anyone use the API tap water filter............especially for nitrate removal? My tap water contains +40 ppm Nitrates, so there lies my problem! "
I need a filter to remove the Nitrates. Any recommendations on a filter or comments on the API filter?

Plants that grow a lot eat up nitrates.

Would the plants absorb enough Nitrates to get the level below 20 ppm? What plants are best?
