Your levels are coming up... Do serious water change and then follow up with a series of 25% water changes in the following month..And then buy a denitrifier natureef if you have over 10 fish.. If not don't purchase a reactor...that's all...Just kidding but do the water changes...

I'm sorry it lokks like you have a fairly new system just do the water changes..
