I’m currently on my third going to fourth week of cycling and my ammonia reads .25 and nitrites is a deep purple kinda hard to tell which one it is and my nitrates is about 10-20 ppm and it’s been stuck like this for about a week. I did a 25% wc then a 50% 2 days after and it’s still reading the same levels has my cycle stopped due to high nitrates I read on another forum high nitrites can cause for the process to slow. Any advice or comments would be greatly appreciated !!!
