1. How to manipulate them with fish feed
Nitrate Levels in Aquaponics

2. Fish feed comes in a variety
of protein levels.

3. The protein level in your feed
can impact your aquaponic
system’s nitrate levels.

4. You can purposefully manipulate
the nitrate levels in your system by
changing your feed type or feed
levels.

5. This is important because nitrate is
what plants take up as a nutrient.

6. If your plants are growing
healthy, but your nitrate levels
continue to rise...

7. ...you have too much nitrate.

8. If this is the case, then you need to
reduce your nitrates.

9. You can lower nitrate without
sacrificing weight gain for your fish by
just going with a lower protein feed.

10. If your plants are deficient or your
nitrate levels are dropping, you need
to add nitrate.

11. You can do this by increasing your
feed or by using a higher protein feed.

12. In summary...

13. Want LESS nitrate?
Use a lower protein feed or feed less.

14. Want MORE nitrate?
Use a higher protein feed or feed more.
