....Nitrite. I have a 10 gal tank, 16 days old. Things are going fine, been testing the water almost everyday. About 3 days ago the Nitrite has been high.
Today I did a 25% water change. Tested it again and the numbers are still high. Anything I should add to the water to lower that?
It has 6 Cory's and 1 betta in it. 2 live plants, running a Top Finn 10 filter (I changed the cartridge in it last week).
