Finally hit the point of panic with my 120g ProStar
Dec 2023: Largely Happy Reef Tank for years. Dosing A4R. PO4 a bit high at .35 PPM, nitrate near 0, only issue is some turf algae and coral aggression
Jan 2024: Decide to start dosing NoPox to see if PO4 would come down a little. Concur that I should not have dosed NoPox unless both nitrate and phosphate were elevated. Dosing 1.0 mL daily.
3/18/2024: Dark spot starts forming on seasons greetings monti, zoanthids next to Forrest fire digi partially closed, discontinue NoPox
3/31: Tissue death evident, brown spots growing
4/30 Forrest Fire Death
Stylo starts receeding
Today: About half colonies in tank continuing to recede. Mostly affecting SPS (acros, montis, leptosaris), plus a few zoanthid colonies. LPS like torches, candy canes, frogspawn seem resilient.
Attempts to fix:
- Started with assumption of unknown toxin in tank, ran Rox carbon in media reactor for two weeks and aggressive water changes, 200 or so gallons last month
- 3 treatments of EM Erythromycin past 5 days, tissue decay unaffected
Pretty tragic and stressful. If anyone has any thoughts please let me know.
Alk: 8.5 dKH
Calcium: 430 ppm
Mag: 1440 ppm
NO3: 0.5 ppm
PO4: 0.27 ppm
