Title says it. I'm mostly through the cycle, ammonia is very low, nitrite is extremely high, I just put in 40lbs of live sand and I'm going to add bio spira in a few days. I have some rock which I've bleached and cured and washed a thousand times. Is it safe to add more into my aquascape at this time? I don't believe that they would leech any nutrients out. Below is my latest photo but it is still cloudy from the live sand. Just turned the filter sock on the get the rest of the cloud out since it's been a few hours already. Thanks in advance for the advice!
