I understand you
Well, I noticed that my cycle was running smoothly until I nitrite hit the 5.0 then, it just stopped. I's suggest doing a massive water change and just raising ammonia 10 the .50. for some reason it seems to go faster when you have the levels at low.
for now just observe. If the ammonia starts lowering, but you dont see an increase in nitrites, it is because you have all of your nitrite-eating bacteria present and I'd say your cycle is complete!
some people seed their tanks so well that they never see a nitrite spike... and they keep waiting, and waiting thinking that their cycle hasnt even started!
C'mon! Cheer up! i know it is horribly frustrating but im sure it is almost over!
