It has now been 2 weeks since I set up a 29 saltwater, 40lbs crushed coral/dolomite, Stability(which was used twice within the first 2 days) by Seachem, Stress coat, undergravel w/1140 powerheads, 1 Mag 350 canister, 1 Eheim Wet/Dry canister, 1 seaclone 100 protein skimmer. Tank has been cycling for 2 weeks now with 1 panther grouper, and 2 damsels being fed generously twice daily, no water changes, only top off of evaporation. Now my concern.....After the first week, my ammonia levels read 0.50 ppm
with Nitrite not even registering, Now on the second week, Ammonia levels (according to accompanying chart) are undectable 0ppm, same with Nitrites. Fish are looking healthy, alert and active, and eat regularly.
This is where I am concerned, what happened to the ammonia spike, followed by nitrite? 2 weeks, 3 fish, fed twice daily??? A minimal spike in ammonia the first week, then a complete drop the second?? Is their a remote chance my tank has cycled or am I dreaming? Please respond with any explanations.
