Green Wall Hammer Acting Wierd?

[gaetyn]

Hello,
I have a question about my Green Wall Hammer's behavior the past few months. During the day my hammer has very long and thin pollyps. It kind of looks like sweeper tentacles. Is this normal? At night it closes up and "goes to Sleep" like the rest of my corals. My params are:
tank sixe 55 g
temp 81
specif gravity 1.26
nitrates 0
nitrites 0
lighting 4xt5ho (3 ati blue plus 1 ati coral plus)
calcium 420
phosphate .25 via api test set. this is high but i recently started runing gfo to help lower it.
I do a weekly waterchange of 6 gallons with ro water using kent salt
My other corals and inverts are doing fine. Any input would be great

Very normal, just gathering food is all!

Looks super happy to me. How long has your tank been up and running? ( just curiosity, probably not relevant to your question)

It's been up and running for over a year. Currently I only have LPS soft corals and mushrooms. Also a pink tip condy anemone that my tomatoe clown loves. I want to move in to the SPS world but I don't think I have enough lighting.
