Here's a quick summary of the cycle:
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
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.
Yesterday also added one bag of Purigen....water looking much clearer (was slight whitish cloud...now back to a very mild yellow-green and getting clearer).
Today is day 32 BUT, the nitrites still 5 and nitrates 40.
What am I missing? Time to pwc 20% ?? Then, what?
