Hello all, a little guidance please. The nitrate level in my mains water supply in the test I did today is between 40/80ppm, so frequent water changes would not appear to make very much difference to the residual value that is in my tank. Any recommendations by anybody would be appreciated. I have just seen advertised by Tetra a product called Nitrateminus which is granules that are added to the gravel, anybody had dealings with this? S.
