Nitrate Dosing Question
I've been reading up a lot on fertilizers the past week or so, and it's been hard to wrap my head around, but I think I've got most of it figured out. My question is related to KNO3 dosing.
If my tank is pretty well stocked, will the fish provide enough Nitrate levels for the plants daily, and do I risk overdosing and creating a harmful environment for my fish if I add more in form of a dry fertilizer? I'm already dosing P and K, as well as micros, and I'm also afraid of creating an imbalance if I don't add N on. This is a 20g long with Excel and low-medium light, so I'm only dosing lightly for the above anyway. My tap water has a KH of about 4 and a GH of around 3.
Hopefully this isn't too dumb of a question, I've gotten most of my answers searching the forum but this one is a little harder to word correctly.
I'm going to be adding German Rams soon and I've heard they're sensitive to water chemistry, so I thought I'd ask here first.
I'm doing weekly water changes between 25-40%
