My tank had a setback back in 10/2020 where I lost the ability to keep any SPS and many LPS. To this day I have not been able to identify the reason. Odds are small but in case it’s microbial in nature, I was hoping that some kind soul on here would be willing to throw a few sponges (which I would of course provide)in their sump to seed with their tanks healthy BB. It’s a Hail Mary but it’s something I’d like to try. Thanks!
