Six days seems a little too quick for a cycle to complete. unless a lot of established LS and LR were used.
It usually takes 2-4 weeks, depending on tank and method.
Let it go for few more days and do daily ammonia and nitrite checks.
Not everybody checks every day but it is a good idea to check every couple days while cycling to see the development. Typically you will see spike in ammonia, with little nitrites, then as the ammonia goes down the nitrite goes up, the nitrites will then start to decline until both ammonia and nitrites approach zero.
By checking periodically you are able to see this trend. your not stupid, just learning like the rest of us did.
Good luck......MCF
