I know of a couple of tanks (including my own SPS tank) that were long established (new tank OK) and then started zeo and lost a lot of SPS. My tank lost about 450$+ worth of SPS in one week. It all looked OK for a while after zeo was started and then all SPS (most colored once) were just gone.

Also 4(!) AI modules might be a reason as pple mentioned before.
