Monti Cap Help

[Der ABT]

well as requested,
its still seems to be alive, still not really getting its color back but not white,
the Acro is still showing a bit of flesh tearing from the bottom up, one stalk is full white, may be a K+ deficiency but i am still thinking it was from the Phosgaurd.

have new bulbs, RO, and a phosbanreactor coming in the near future.
here are the pics

Looking at the other pictures, the tank is looking good. I wouldn't worry too much about the monti cap and the acro branch. Bad things happen quickly, and good recovery, growth, and color take time (weeks-months).

Don't try chasing obscure things like potassium levels. Just keep up good husbandry practices (water changes, skimming, not overfeeding, maintaining Ca/Alk, etc . . . ) and you'll be fine.
