I have a fairly heavily planted tank with RAMs in it. I have heard that they can even be a bit sensative to nitrates, so I do frequent water changes. My question is this: If I use liquid fertilizer is this going to raise my nitrate levels when I do the nitrate test on my water? I think it would because fertilizer is just nitrates, right? Am I wasting my time by changing the water out because the nitrates are a little high and adding back in through fertilizer? And will the nitrates from the fertilizer bother my RAMs. I quess there is more than one question there. I am just worried I am doing more harm than good by adding the fertilizer.
