Anthony, I did similar to what you did but mine was two weekends ago and my other tank had gone through the cyano and was gone on it's own before I switched everything. I added 30lbs of sand at this point nothing else. Getting some surface algae on the sand but that's it. CUC is keeping up with everything. Going to have to hookup the elevator to get the blue legged hermits out of the sump LOL One got migrated up today.
Oh and I FEED my tank, Feed it well.
