How long did you have them before you started moving them around?
Sometimes GSP can take a few days to come out at all let alone fully
expand. Leave them alone and see what happens. If it's more than a
week then move them, but don't panic.

How much flow do you have in your tank? GSP likes moderate alternating
flow. Your params are OK. There is no need to keep doing water
changes. You'll want to reduce the PO4, but water changes are to
remove nitrates (which you have 0) and replace trace elements.

Do you have a skimmer?

Your temp is not the problem. It's probably your lights. How much
lighting do you have? Have you tried making a large water change to see
if that helps? Have you verified to make sure that your hydrometer is
measuring correctly?

The capnella, button polyps, mushrooms and xenia are all doing fine
under the lighting (although I am sensitive to the need to maximise
this) - the LFS do not think that the lights are the issue....certainly
a move to T5s can be done easily...there is not sufficient clearance to
put in halides - the tank is in the kitchen....I currently have 3 T8
flourescents giving 3W per gall....not the best but from my
understanding should be sufficient for the Star Polyps as well as the
other soft corals that I have. I deliberately am not purchasing anything
with high light requirements - I'll save them until I convert another
larger tank and can add the halides. Now, one thing on the lighting is
that the Star Polyps in question were kept in the tank with the halides
at the LFS - and I have asked over and over if that might be the issue -
ie. they are struggling to acclimatize to my lower level of lights and
keep getting the answer "no" - right now they swapped the first colony
for another (slightly more expensive) colony so I'm not losing but I
just don't like not seeing any creature in my care not thriving.

The hydrometer is calibrated to 25C so there is some degree of
inaccuracy....it's a very basic swingometer type of thing (Red Sea) -
I'm thinking maybe I should get something a bit more sophisticated....it
tends to stick if left in the water for any length of time and needs a
good rinse before I would even start to trust it (I think this was the
first lesson I learnt when I originally set up the tank prior to adding
anything other than water and salt).

I made a 15% water change yesterday morning....it was the lack of any
difference with the star polyps that prompted my call to the LFS....
