Acros Peeling @ Tip

[catman78]

Hi All,

I have a few frags that appear to be healthy.
Color and Poylp extension if great,
however I see some have tissue pealing at tips.

I have an MP40 @ 75% reefcrest mode around 1 ft away
from most of the Frags

Params:
No red bugs

Cal 430
Alk 8
Mag 1400
N&P 0

Have been using Tropic Marin Bio Actiff salt for last five 25% water changes.
Also been running NP Pellets for 6 months

Wondering if I stripped water column too fast?

Lighting: Five 48" T-5's on Icecap 660's and one 100% white Reefbrite strip. Lights are 6" above water.

Any ideas

I have seen a similar issue after trying biopellets. The corals got significantly lighter in color (almost bleached) and a slight burn on the tips of corals closest to the vortechs. Keep a close eye on your alk so that it does not rise above 8.5dkh. You corals may need time to adapt to clearer water, and reduced nutrients in the water. I also feed a ton more now than I ever did with no NO3 or PO4 measurable. I do dose AA and CV from Zeo. HTH

Burning and peeling look the same?

Is it peeling or white? My corals tips get white when they are growing.

My parameters are pretty close to yours and I experienced the same issue when using Bio Active salt. I used it for about 2 20% water changes. Went back to regular IO and the problems went away.

Oh I also have been using the np biopellets for about 5 weeks now.

Any others have issues with TM Bio Actiff?

I think I'm going to cut usage in my next change by 50%.
