So I have came to the conclusion that my RBTA is gone. It has been 3 weeks and now I am starting to see a slight increase in Nitrites. They were always zero and yesterday they weere 0.25. I did a 15 gallon WC on a 65 gallon tank. After rock work I would say its about a 55gallon total system. Tested again today and still have 0.25 on nitrite. Would doing another 15 gallon be fine two days in a row or should I wait a few more days? Ammonia is still reading zero.
