Thanks for all the replies guys. It just seems like something is amiss. I've been doing 50% PWC TWICE a day for a very long time now (last 3 weeks out of a total of 8 weeks) and nothing seems to be changing.
I get up in the morning and test my water. Ammonia - .25, Nitrites, .5-.65 so I do a 50% change.
At night, I do another check. ammonia .25, nitrites .5-.65 so I do another 50% change.
Rinse and repeat. Also, the ammonia is from chloramined water. I believe it's a false positive from Prime. After a full day, my ammonia is completely gone (but at the expense of my nitrites going sky high).
Am I just overstocked? I have 6 cherry barbs and 3 rummy-nose tetras in a 20H. I just can't believe this cycling is taking this long. My ammonia bacteria seems to be well-stocked, just not my nitrite ones :*(
PS - I am seeing Nitrates so I guess I do have nitrite bacteria.
So the consensus is water changes DO NOT SLOW down the cycling process?
