Could my tank have cycled in 4 days?
I set up my 12 gallon cube on Sunday and today I tested the water and I found:
Nitrate 5/10. (It's hard to tell)
I have been testing the water daily and on Monday and Tuesday my ammonia was 0.5 but my nitrite has stayed at 0. My nitrate also read 0 until today. I have 17lb of cured, established live rock from a friends tank and 10lb of live sand. I really don't know what is going on so please could someone help me out! I'm not going to get any livestock soon and I'll keep testing my water to see what's happening.
