Hi, suddenly I see a change in my nitrite level where its at 1 ppm and nitrates have dropped to zero.

Ammonia is as usual as 0 to .25 PPM. I have lately been seeing a lot of fin rot in the fish (Tilapia) as well. is this probably because of the increase in Nitrite?

Sorry to hear of your troubles.

What were the typical levels prior? What other changes have occurred excluding fin rot. Ph, weather fluctuations, turbidity, smell? How are the plants faring?

The more detailed analysis/info from your end, the easier it is to assist in a diagnosis.

How old is the system?
