Green Slimer Responding to light oddly

[PirateMonkeyReefer]

Hello! I've got a little mini Colony of Green Slimer that has been in my tank for around a month or so. For most of the day's light Schedule, the Polyps have a nice extension but when the warm and cool whites peek for around 4 hours the polyps recede. The other SPS in the tank (a Purple Piccilopora and ORA Bird of Paradise) And the other corals respond very well to the additional PAR and spectrum that the whites offer and it actually helped their coloration. All of my parameters have been rock solid, but the system is still young at 2 months and is a tank transfer from a 40 breeder with some 7-month-old rock and sand (which now resides in the refugium) Below are system details.

200 gallon deep dimensions

Salinity 35ppt refractometer

Alk 9.2 - Hanna
Calcium 420 - Red sea
Magnesium 1400 - Red Sea

Nitrates 2-3 - Red Sea
Phosphates .04 - Hanna Ultra-low Range

Light
5 Radion XR-15 Gen 5 (two on the left, 3 on the right
4 Orphek OR3 Blue Plus Light Bars

Can you maybe post a couple pictures? I agree with you that a lot of acros respond very well to higher par so I wonder what’s going on!

I think it is most likely getting too much light during that peak photo period. Have you par tested the tank? I'd move it to the bottom of tank where there's no hot spots.

I haven’t since I added the 5th light maybe I should move him. It’s odd though as the purple piccilipora is pretty happy and they enjoy high par as well right?

 

[Reefahholic]

Is this still accurate? Where is it sitting?

 

[PirateMonkeyReefer]

No this is a new tank

it’s sitting on the shelf rock to the right. This is pre 5th Radion XR-15

Ok. Move it to a lower PAR area and see what happens.
