Help with Nitrate after change is still high

[pettygil]

Help with Nitrate after change is still high. I am past 40 ppm after water change on my 6.5 gallon tank with one Betta. How do I lower the Nitrate.
Thanks.

Whats you typical water change schedule? How much, how often?

Are you overfeeding? Once a day no more than is eaten in 3 minutes.

Is there any nitrate in your tap water? If so, how much?

Nitrate can only be reduced by reducing ammonia, changing contaminated water for cleaner water, and having live plants. There are also chemical media you can put in your tap water that absorbs nitrate.

Are you seeing any issues with your betta?

While lower nitrate is better, fish are a lot more tolerant to high nitrate than they are to high ammonia and nitrate. People regularly sucessfully keep fish in high nitrate conditions. If you are taking reasonable measures to keep nitrate low, but your fish are fine, is it a problem?

I change every couple of days, like 50 percent of water.

Yes. i only feed once a day, just a pinch of fish food.

No nitrate in my tap water.

No, betta seems fine to me.

My bettas seem fine. I checked on them both, they seem to be ok. I have 2 6.5 tanks for my bettas.

The same thing applies to your small tanks as it did in your large tank thread. Ammonia/ammonium is the start of nitrate production. You must reduce those to reduce nitrate. There are nitrate removing products for filters ( i.e. Poly filter pad, API Nitra-zorb, Acurel nitrate absorbing pad, etc), certain live plants that use the nitrates more than others ( i.e. Marimo moss balls, Guppy Grass, Duck weed ( be careful with duck weed as it will get overgrown in a tank) ) or house plants like Pothos or these (
