Ok so my tank has been running for almost 2 weeks... I have a total of 60 lbs. of CLR and 40 lbs of LS in my 55 gallon... I had an ammonia spike of 1.0 about 4 days ago and tests today show 0 ppm Ammonia, 0 ppm Nitrites and 20 ppm of Nitrates... I think I am going to wait till the Nitrates drop to about 5 ppm before adding anything... Also, I can't get my PH above 8.0, right now it is sitting at 7.8... Any thoughts, I added my 8.2 buffer but it won't stay above 8.0... Should I add ammonia to get a more toxic level to see if the CLR can handle it before adding any livestock, like maybe get it upto 4.0 ppm and let it drop again... Any thoughts would be appreciated... Thanks...
