aquarium pharmaceutical nitrite reading problem

50-75%.
 
anytime....fell free..that's what we are here for.


Settled on what fish you will be getting?
 
Yeah, probably about 5 neon tetras and a betta. I have a 10 gallon. Also, if my readings are good tomorrow do i need to do another big water change?
 
if the nitrites are not at zero and an increase on nitrates, I'd say yes.
