I just did a water test because my fish were acting unusual and found out I have a nitrate of 20. What causes this and what can I do to reduce it? Thanks for your help!

To reduce Nitrate you need to do a water change and if you want to keep it low if it reguarlly gets that high then you need plants to use it up.

It you have constantly high Nitrate then it means that you're tank could be overstocked...

you may also want to test your tap water to see if there are nitrates there

Nitrates are the by-product of nitrites. As long as your ammonia and nitrite stay at 0, you might just need to do water changes more often.
