Hello everyone :wave:
First off a bit of info into the cycle:
Fishless cycle began 9.26.13
180DT
75 Sump
180# dry rock
40# live rock (couple nice hitchhikers, small feather dusters and some pods all seem to be doing well... think I have a few small vermetid snails also, not sure about them yet)
200# aragonite special grade sand
SRO2000INT - Running duration of cycle
2x Tunze 6100.1
1200gph return
My Log (I'll just depict the highlights rather than the entire log):
10.5.13 pH 8.2 NH 0 NO2 0 NO3 0
10.10.13 pH 8.2 NH .5 NO2 0 NO3 0 - first ammonia reading
10.13.13 pH 8.0 NH 1 NO2 0 NO3 0
10.17.13 pH 8.0 NH 2-4 NO2 0 NO3 0
10.19.13 pH 8.0 NH 4 NO2 .25-.5 NO3 0
10.22.13 pH 8.0 NH 1-2 NO2 3-5 NO3 20-40
10.24.13 pH 8.0 NH 0 NO2 5+ NO3 40
10.27.13 pH 8.0 NH 0 NO2 5+ NO3 40-80
10.29.13 pH 8.0 NH 0 NO2 5+ NO3 40
10.31.13 pH 7.8-8.0 NH 0 NO2 0 NO3 0-20 (looks like my cycle is complete?)
(** I'm confused, where did all my nitrates go? I have not done a 50% water change yet, is my skimmer removing them all?)
(double check from other side of tank)
skimmer running, I emptied it once a week and changed filter socks once a week during cycle.
overall view
Now, if my cycle is complete, can I go ahead and add a CUC? My 40gB QT tank is only about 10 days into cycle (hindsight should have done the QT first, oh well whats a few more weeks its already been 7 months) so it will be awhile before I have any fish but do you need to QT the CUC also?
