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 +

What is the level in your tap water? Liquid test kit, in date?

Test your tap water for nitrate and post the results.

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.
