Galaxea bleaching

[Tikosyn]

Hi Guys,

So I got a long polyp galaxea coral on Friday from Diver's Den along with 3 other corals, all of which are doing well with the exception of the galaxea. It has yet to open up at all, haven't seen a single polyp and looks like it is losing flesh/bleaching. I originally had it on the sand bed but thought it wasn't getting enough light so moved it up, bleaching got worse so moved it again, etc.

Tank stats:

Red sea reefer 750
Flow: 3 tunze nanostream 6095
lighting: 4 AI hydra HD

Alk 8.4
Nitrate: 2ppm
Phos: not sure
Calc: 430
Mag: 1370
ammon" 0
Nitrite: 0

Not sure what to do, anyone offer some advice on how to make a galaxea happy?

Keep it on the bottem tank for a week or so. If it starts browning. Check your phosphates ir can be from lighting being to low. Move it a couple inches higher if the that's the case. Don't put it to high or in the middle of you tank or you will stress it out and it will bleach out. They don't require a lot of lighting I've always seen them in the bottem sand bed. Try keeping it away from other corals as well.

Without nutrients he may be bleaching just due to the lights being on.

2ppm Nitrates is probably equal to zero if you consider the accuracy of your test kit.

Check phosphates because if they are also zero, your coral is going to have thin odds of making it unless you make some changes.

If that's the case...

Take any "extra" filtration offline....keep only your skimmer.

Get some nitrates and phosphates from (e.g.) Seachem or Brightwell and dose up to ≥ 5ppm of nitrate and ≥ 0.10 ppm of phosphate.
