hey that looks nice, wide open swimming space, low fish bioload, open corals agreed its looking great
pictures are always worth a thousand cycling words heh
the minor growths in the new system are visual benthic growths, cycling verifiers.
if all the rocks have spent equal time in that system, and any of them have the common new growths a bright fed reef will have, by rule of order of deposition the filter bacteria were done and ready before those growths. the filter bacteria are part of the base layer, initial layer, that supports the top growth for the things we can see as pigments, slimes, diatoms, algae etc.
we can tell your reef is totally cycled off the pic. these collective clues are how we get away with never, ever testing for ammonia or nitrite mainly out of pride and secondarily because they're always predictable in that nitrite doesn't matter, and ammonia is controlled due to several markers met other than the test levels.
at no time will a reef given time to take on new benthic growths fail in basic nh3 control, says seneye. and because all tanks behave this way, packed in wet surface area, they all trend the same for ammonia. no outliers.
