So I found a sera nitrite testing kit at my local flee market any one have any experience with these are the a good accurate test
 
If it's too old it won't give true readings. You could take a water sample of your water to a LFS and have them test your water then compare your readings.
 
The last test I took to lfs said 0 nitrite and so did this test bout 3 days difference
