TL;DR
RedSea MaxNano purchased early-April, cycled, and was ultra-low nutrient. Minimal stock; minimal feed. Dinos appeared and caused the death of a Two Spot goby, an emerald crab, and some hermits/snails. I fought dinos and won with a combination of UV Filter + adding pods, phyto and sand/mud from IPSF.
Corals are now stressed across the board - and I'm curious why and what my next steps should be.
Signs of coral stress
Parameters
Salinity - 37.5 ppm
Temp - 29.8
Ph- 8.6
Nitrate - 20
Alk - 10-11
Water changes weekly of 2-3 gallons.
Lighting
The 23K out of the box program from RedSea's ReefLED50, running around 73% of max on an acclimation program. Ran the lights less for a week or so 20ish days ago to combat the dinos.
Theories I Have
Execute a 20% water change today. Keep water changes to 4 gallons weekly until things improve. Monitor nitrate/ph/alk every morning.

Signs of coral stress
- Octospawn completely bailed out
- Toadstool has "deflated", fallen over
- Cyphastrea bleached
- Zoas/Ricordea receded
- Torch polyps retracted
- Acan + Caulastrea showing some tissue loss

Theories I Have
- Temperature - It was hot in Seattle last week. I was out of town and my wife was handling feeding/top-off. Maybe the tank just got way too hot.
- Nutrient swings - going from ultra-low nutrients to higher nutrients in 20ish days could have stressed everything out.
- "Chemical issue" - Octospawn bailout stressed everything else out. Timeline was: wife noticed bailout while I was out of town; next day cyph bleached, candy cane/acan looking terrible, everything receded/looking ticked.
- All of the above - this is the clubhouse leader.
