Spring coral losses

[untamed]

I hacked 1/3 off a large pocci last night...expect the remain 2/3 to be gone within the next 48 hours. I'm also on D&D salt at the moment. Lost my rainbow monti in 48 hours last week. Really...I've been losing coral since Xmas.

No measurable parameter can I explain what has been happening to me. (I don't measure potassium). It behaves viral or bacterial and I'm experimenting with some unique dips to see if I can stop the progression on sample pieces. So far, iodine based dips don't really seem to be helping.

Meanwhile, I have 4 or 5 other acros (mostly millis) that are thriving, growing rapidly and look fabulous! I'm baffled.

You know...the best results I seem to have were with Ocean Pure Pro....go figure.

If D&D salt is truly manufactured by evaporative process...is it possible that this can introduce some naturally occuring bacteria/virus that can overwhelm a weak SPS? Just a theory...
