is this too much nitrates by the end of the week?

I been feeding every other day and dosing.

I end up with 20-30 ish nitrates using api master kit to test.

Is this too much nitrates? Would my fish feel any discomfort from this? At what point do nitrates start to bother fish?

If you're doing water change by the end of the week, then it'll be reduced. I would like the nitrates between 5-10 ppm, 20ppm is not bad at all.

50-60%? That's good.

And eh, 20-30ppm is nothing to be worried about. I's say it's around the 40-50's and beyond is where you should seriously begin to think about how to really lower it, but right now, you're fine.

Someone on here told me this and it seems to be working out.
If the test is yellow or Orange it's good but when it turns redish it's too much.
K2SO4 can be substituted for the KNO3 you are dosing to reduce it some.

The shortest distance between any two points is a straight line...in the opposite direction...

I dose EI but not Kno3, just K2so4 and Po4, fish waste and food seem to be enough to cover the No3.

Yeah, its 0 nitrates.

I am a little overstocked which is why my nitrates climb. I still have room to plant more things which would use up more nitrates. I feel as the tank matures with more plants the nitrates won't be a problem.

You might always have a high nitrate problem while over stocked. I did when I was over stocked. The fish didn't seem to mind. I ended up getting a group of Otos to help keep the algae in check.

I am hardly overstocked and I think I have a solution.

I am going to add purigen to my filter right after my next WC once I got my nitrates down to 5ppm ish. I figure I can use this to eat up organics and allowe to dose my ei ferts to control ideal nitrates.

Once my tank has matured and the plant.mass is near max capacity, which I figure 4-6 months should be plenty of time. I will remove the purigen and allow the mighty plant mass to control the organics at that point. The ideal is that once filled with plants the organic will not build up or at least not as much.

Thoughts?

Why not just dose a little less KNO3?
Then the NO3 won't climb quite so much through the week.
As the tank matures you can adjust the dose.

Does not make sense to me to remove stuff one way and add it back the other way.

It's pretty technical but this 5 part video series got me up to speed on nitrates if you want. It's a lot to sit through but in case you have the time these 5 vids helped me.
