Nitrate in tap water
I am having troubles with having Nitrate in my actuall tap water!
I have noticed for a while that no matter how many water chages I did I allways had Nitrate in my tank. So I decided to test my tap water and to my horro found that it had quite hight Nitrate coming from it (about 10 - 20 ppm). I have been having trouble of late getting my plants to look really healthy and I feel it might be due to this as well. Gus (a member here too) who lives near me does not have this problem with his tap water so I am guessing old pipes that are causing this.
Anyway does anyone know of how to remove Nitrate from your tap water? I know you can do this with a RO water filter and I am looking at getting one when I can afford to, but as they are expensive I was wondering what I could do in the mean time.
Any help much appriciated, Cheers....
