I started my cycle (75g tank) a week ago by adding 30kgs (approx 65 lbs?) of live rock and threw in a couple of raw shrimp. The live rock was in a giant tub at the LFS
with good circulation, but the guy from the LFS
said it had been there for about a month and would be perfect for cycling.
Water is at about 26 degrees (80F?) and all my equipment is on (see my info). Been testing for ammonia and nitrates, and ammonia is barely present, about 0.25-0.50 ppm
and 0 nitrites. When i see the ammonia 'spike' what sort of number in terms of ppm
is normal during a spike? Also how suddenly does the spike occur, or is it a gradual climb over a few days?
Most things i've read say the ammonia should spike after about 4-5 days. what should i do if i don't see a spike in the next couple of days?
