Nitrite in established tank. Need advice, quick.

[zenseed75]

I'm doing water changes daily. I shake the #2 bottle for a minute.

I have another question though, Since the fish with the one blind eye and one cloudy eye he can barely see out of still eats if I feed him with tongs. Anyone recommend any antiobiotic foods? Any success with these?

 

[loaches r cool]

Does anyone else have problems distinguishing between 60 and 80 on the API nitrate Card?

I cant distinguish between 40 and 80 so your better than I lol. The API nitrate test is one in particular that isnt very accurate.
