Is my SPS dissolving?

[jonnybravo22]

What do you think of the above picture? This is a red planet frag. The parts where you can basically see through the coral at the base were not like that when I got the frag a few weeks ago. It was also more red but right now I'm more curious about the structure appearing to dissolve than the color, perhaps those two are related.

This is not unique to this coral, I have at least one other that is doing this also. At the same time, I see growth and new growth tips on some of the longer established corals (blue millie for example). I have other corals that have not grown at all in 6 months. What do you guys think this is and what should I do about it? I think my parameters are in line (other than phos) but not sure what to make of this.

I know I have some algae. I have been beating it back week by week with manual removal and GFO but you'll see it in the pic above. Any help is appreciated.

Parameters:

phos - 0.12ppm (hanna test kit, using GFO to bring this number down)
cal - 420ppm (elos test kit; dose 2 part on dosing pumps)
alk - 10.4 dkh (hanna)
Salinity - 1.026 (refractometer, calibrated)
temp - 78- 81 (profilux probe)

thats so weird i have one of my corals doing this too. the polyps are coming out and its colored nicely mine is a little bigger, but the bottom on both sides are doing the same thing. my parameters are good, your phos is a little in sps system imo but thats not cause this i dont think.

The only time I've had that happen to me it was due to an excessively long dip in revive

I posted in your duplicate post (different forum).

I feel and share your pain since I have a few doing the same thing(one being a rp as well).For me I was leaning towards red bugs but I dipped in bayer and didnt find any. I cant explain it its almost like a bacterial infection but I have no way to prove it.My paremeters have been solid. I also have no fish in the tank due to an ich outbreak.But I have been feeding corals with roti's, reef oysters ,and so on.One thing I do have to admidt is I have been lazy on the water changes.
what are your maintenance habbits?
