Brand new user, Brand new tank - first post....
I just installed 70lbs uncured live tonga rock into my 90gal tank on Saturday around lunch, then turned on the filters. I tested my levels Sunday evening:
SG - <1.025>
Nh3/Nh4 - <5.0>
N02 - <0>
N03 - <0>
Ph - <7.8>
My ammonia is high, but not a huge suprise since this is the beginning of my cycle.
I'm wondering how long do I wait (and let the ammonia possibly climb some more?) before changing some water out - also how much would you swap the first time? (I run all my water thru an RO and mix salt prior to putting in the tank).
Thanks in advance.
