I can't get the nitrite to go down even with the 50% water change. I have no clue what to do, just keep changing the water each day and how much is safe 50% or less? I don't want to stop the cycle process but also want to help the fish if possible.
Provided you use a good water conditioner (you are), and there is no disparity in water parameters (pH, hardness, temperature) a partial water change up to even 90% will not harm the fish. Just don't disturb the surfaces when you do them. Bacteria colonize every hard surface, tank walls, each grain of gravel, filter media, plant leaves, decor...just change the water and this will not be affected.
