Administrators Cory Posted December 22, 2020 Administrators Share Posted December 22, 2020 You change water and stop feeding to lower nitrites. Link to comment Share on other sites More sharing options...
Hobbit Posted December 22, 2020 Share Posted December 22, 2020 How long has the tank been running and how long ago did you add your fish? Also have you tested whether there’s nitrite in your tap water? I’ve never heard of that before but it might be worth ruling out anyway. Link to comment Share on other sites More sharing options...

Before the fish it was running and cycling for 3 months. Link to comment Share on other sites More sharing options...

Did tou mean feed less and only a few times or stop feeding all together? Link to comment Share on other sites More sharing options...
KoolFish97 Posted December 22, 2020 Share Posted December 22, 2020 Stop feeding completely for a few days (3 or so)then feed lightly do a few water changes and just make sure your not over cleaning the filter/tank and causing "mini cycles" where the system struggles to catch back up also make sure your not washing your filter in tap water which can cause these mini cycles Link to comment Share on other sites More sharing options...
Andy's Fish Den Posted December 22, 2020 Share Posted December 22, 2020 I would test your tap water and see if there is nitrite in it. With having the filtration, live plants and doing water changes twice a week already, I suspect there is something going on with the water you are putting in the tank or that you are way over feeding. How large are the water changes you are doing? Link to comment Share on other sites More sharing options...
Socqua Posted December 22, 2020 Share Posted December 22, 2020 When you say understocked goldfish tank, can you clarify? How many goldfish, what size are they, and what size tank? Link to comment Share on other sites More sharing options...

How many goldfish, what size are they, and what size tank? Guessing they mean overstocked. 3ppm nitrite is super toxic, so dose extra prime and change a lot of water until it comes down. Also, don’t underestimate goldfish and their water change needs. Our two breeder orandas needed 90% weekly and 10% daily (auto) to keep nitrates at 20ppm in their 75gal tank. So even if you’re doing two changes, if those are 20% etc changes the tests are showing that’s not enough. If you’re still getting nitrites you have very dirty filters, they’re undersized, or you never finished cycling.

You probably already figured this out, but you probably need to bump that percentage up, and also do it more often. 1 Link to comment Share on other sites More sharing options...
