Subject: Re: Problems with cycling/water tests by Daisy on 2011/7/6 17:24:53 With your nitrate test, try banging the bottle a few times on a table before yo do all the shaking. The contents of the bottle can get stuck and not mix properly and if this happens then the reading will be wrong. Have you used any medication recently that could have affected the bacteria? |
