Tank has been okay, I went on vacation/work trip a couple times in the past month and got an odd mini cycle.
Pre-vacation: 0 nitrates but generally happy corals and daily half doses of neonitro and neophobia
Vacation 1: tank sitter (minimal frozen food and no nitro/phos) and auto feeder with TDO pellets. Returned to still 0 nitrates but generally fine corals
Began feed heavy and dosing neo/phos at half dose with almost daily testing
Corals all began shrivel (especially hammers and mushrooms) lost a couple small acros. But torches have had minimal issue with all this (maybe because they can process ammonia better?)
2 weeks of continued heavier feeding to raise nitrates still testing at 0ppm and .01p phos with 2 kits
Clownfish showed signs of gill issues and thought to check ammonia.
Ammonia was at 0.4ppm, 20% water change, flushed canister filter and sponges. Ammonia is down to 0.2 and clownfish and corals seems much better.
Other 3 fish (clown, bicolor blend and 6 line) all seemed unaffected by the ammonia and corals are clearly on the up.
I sent in an ICP too, waiting on results.
Here’s some pics from a post feeding so some corals are closed from that
