Ok for like a week now my nitrites and nitrates are way too high. It is a ten gallon with 15 fry in it. I have a med pleco and feed them twice a day. I am doing water changes each day to help lower them. I also have used prime here and there to neutralize the nitrites. Why is this happening?? Ammonia is 0.25 ppm. Nitrates and nitrates are over 2 ppm
If you are seeing "nitrite" counts then your tank is NOT cycled. It's as simple as that. Changing media/equipment, adding the pleco and higher bioload could all have contributed to a new cycle on the tank. As fishnabowl said, adding the old filter back on (if the media is still good) will help. Or adding media from another cycled tank could help also.
In the meantime, you need to test parameters daily, do large water changes to try to keep the nitrites in check until the tank cycles, and add Prime dosed for high nitrites on a 24 hour basis. This can take time so you will have to keep after it until the cycle completes.
Another option is to move some of the fish immediately to another cycled tank to decrease the bioload. But, you will still have to get those nitrites down before you can go back to normal maintenance on the tank.
Good luck.[/qu
Thanks I am doing yet another water change today and was thinking of moving a few of the other larger fry/juveniles to the 75 Gallon tank. The tank IS cycled and has been cor over a month. The water perimeters hVe just changed in the last week or so. I have lightened the food amount also, but still feeding twice daily since they are growing and need the nutrition
