Nitrate Levels High

[drobbyb]

Just for argument's sake, what size is you tank, and what is the stocking? Something just doesn't seem right with the daily water changes and the nitrate removing resins. You could try a 50% water change and then test an hour later. This should have halved your nitrates. If the test kit doesn't reflect this, then you have a bad test kit.
