After coming back from SFO trip, my tank got bombedwith something to do with water and RBTA exploded i guess. Tried to revive by 50% water change..it didn't help..
Few more water changes still not helping almost all sps gone! About 20to 25 pieces.. more than half are big colonies. I kept the Oregon for 11 years and bonsai for 13..so sad they are gone..
Luckily,all fish alive few soft and LPS.
It's finally stabilized with big loss aw! But will keep at it!!!
