Hello all, currently going through the nitrogen cycle. My tap water reads 0 on all levels, just to create a basis. Doing a fish in cycle, currently up to 6 red eye tetras. On day 11 we got about .50ppm ammonia, 0 nitrites, and prob close to 1ppm nitrate. Next day it was around .75 ammonia, same levels for the rest, so we began water changes. Yesterday back to a solid .50ppm ammonia. On todays test, if it is improving, (.50ppm ammonia or lower) should we continue the water changes? My gut says if its working and improvint the ammonia levels, keep doing it, but i dont want to put unnecessary stress by over changing the water
 
Target should be ammonia + nitrite combined no higher than 0.5ppm.

If you are seeing 0.5ppm ammonia and zero nitrite no need for a water change.

If you see a little nitrite alongside your 0.5ppm ammonia or your ammonia creeps up above 0.5ppm on its own then change some water to bring it down to that 0.5ppm combined target.
 
Just don’t add any more fish yet until the numbers are under control as per Aiken’s information.
