question about this piece (sorry i dont know names)

[Joeb]

so ive had this thing for a few months now about a week or so ago I noticed the green tips are fading and the polyps seem to be shrinking.
water parameters are good (ill retest tonight and share the numbers)
do you guys thing this is new growth or bleaching? I have a radion and this piece was in the middle of the light. do you think it it getting too much light? I moved it into the corner to take the pic and also to get it out of some of the light.
sorry for the vagueness
Also happy fathers day to all!!

also here is a link to another thread with a friends lps I am having problems with if anyone cares to help with thathttp://www.manhattanreefs.com/forum/lps/148633-please-help-me-restore-salvage-my-friends-coral.html#post1356726

Check water params and post it here. Shrinking or disappearing polyps doesn't sound like growth to me. Are there any nearby coral frags that could sting it?

raise mag to 1350-1400
and pending type of lighting it came from it may have been getting to much light

ok I just started dosing redsea reef foundation c. I only put in 50 ml. does anyone know of a calculator for this? I looked on the reef chemistry calculator but that chemical is not on there.
I have a 45 gallon display with a 20 gallon sump I would say total system capacity is around 55 gallons.
