Thanks dosing 2ppm and dosing either every morning or every second morning after testing just to keep ammonia up a bit, as it can read 0 and the nitrites and nitrates are still way too highNitrite has crept up very high, I’d suggest doing an 80% change (taking nitrite down to a more sensible 1.6 and dosing more ammonia.
You aren’t meant to do water changes during the cycle but is ammonia or nitrite get too high it can stall. How much ammonia are you dosing? You don’t really want to be doing more than 2ppm.
