Cycling a 65g since Oct 4 using 57 lbs Pukani rock with lots of detritus. ammonia spike reached about 1.5 fairly quickly.... then dropped fairly quickly as it was 0 by day 12. Nitrites spiked to 5 and have not come down. Nitrates to 40 and have fluctuated between 20 and 40 ppm. So, 5 days ago (day 27), I added a raw shrimp ... to satisfy my curiosity and to prove to myself that there is an active cycle. Ammonia spiked from 0 to .25 on day shrimp day 3 and back to 0 by next day 4. Day 28 did a minor pwc 8 gal when I installed a skimmer and needed to move the sump tank. Yesterday, took a donation of very active live rock from an 8-yr old 90 gal reef tank... lots of coraline pods and such and see now spaghetti worms...and a mini-bud of hammerhead coral seems very happy wide-eyed and open! Included about 3 or so gallons of water too. Today is day 32 BUT, the nitrites still 5 and nitrates 40. What am I missing? Time to pwc 20% and add fishes?
