Nitrate level dropped

Hi, My system has been cycled since October and has been testing fine. Now gradually my nitrate level has dropped all the way down. PH is good, Nitrites are good. I have 4 beds full of mature plants and about 80 Tilapia in the fish tank. Any ideas what I need to do to increase the nitrate level back to normal. Thanks

How is the system doing now, what did you try? I have a new system that has done the same. Not sure if I should get more fish, feed more, or pull some plants.

All of the above will increase your available nitrates.

feed more even if its just rotting it will turn to nitrate. Or feed twice a day instead of once. You could also add more fish. All of those would work just fine.
