'Hi there
we set up a new tank 280l juwel 6 weeks ago and a now have 40 fish as staff members didn't tell us that we should cycle tank before we added all the fish :evil: ! So now we have very hi nitrite and we had hi nitrate. nitrate was reduced with water changes but nitrite is still high. we bought API nitra to get rid of nitrite and nitrate do you think it will work? where should we put? Plus our PH is very low now so i am not sure what to do? should we change water again?
I would appreciate any help!!!!!
Thanks
Liza
