Have 20 gallons of planted aquarium with Hang on filter. Always when i test the water once in every 10 days it has high Nitrate. Today it was 160 + ppm and hence water change. There are 4 neon tetra and other 2 pairs of surfi tetra and one algea eater.

Kindly suggest with suitable solution to control the Nitrate.

I doubt on filter , filter will be cleaned on every week as part of regular maintenance

Here are the below test results :-

Ammonia : 0
Nitrite : 0
Nitrate : 160 +

Well, maybe much, much less ferts than you're dosing., IME. What plants & lighting do you have?

I like to keep my tanks @ ~20ppm nitrate or much less (5ppm?).

If you can figure it out, you will want to fertilize once, or maybe twice a week.

It's a combo of ferts in vs plant growth & water changes. Every tank is different, you need to understand the variables. We'll help you do that as we understand your tank's issues.
