I changed about 50% of my water after the nitate levels had read really high on Friday. Then I retested the water for nitates and the level was still the same. Could this be a faulty kit or am I doing something wrong? It is a hagen testing kit and Inormally got my water tested for free at the lfs. I decided to get a nitrite and nitrate testing kit and the nitrates are extremly high. I should also mention that there are no nitrites in the tanks. I'm worried. Can anyone help me?
