Default teach me about polyp extension

As the title says.

So I have a few choice sps frags in my tank, and see little to no polyp extension they are mid to high in the water column, light peak at about 45% on my ai sol but the only frags exhibiting and PE are my birdsnests what can I do to change this? even my purple bonsai is slightly browned out with 0 PE on a regular basis. Any tips/tricks?

Thanks all

Oh and params
Nitrates less then 5ppm
0ppm ammonia
0ppm phos
440ca
Mag 1360
9alk
Salinity 1.0245ish

Parameter looks good, I would check flow, make sure there isn;t any direct flow on the frags. Also take a look at night and see if there is any PE on then, maybe some thing is irritating it during the day time hours. Worst case scenario I would check for pest like aefw since they go after Bonsai and any smooth skin sps first. I would remove the sps and dip it in a clear cup with revive then observe what comes off. If that doesn't yield any results then you can start trying to feed the corals some oyster feast or just general coral food and supplement with zeovit k balance. I would highly recommand you test the level for k before dosing for that matter any other additive you might want to add.

Total flow is about 550gph give or take as my return pumps is 750gph minus headloss plus my 2 korilia 425s, no direct flow for anything. I know I should know this by now but what's AEFW?

Does that sound right? Lol or do I need to throw my other 2 korilias in too?

Ps I'm at work so I may be slow to respond

Acro eating flat worms...not a good thing to have when you have Acro.

Double this.

If there are any fish nipping at the polyps, that would be my first guess if there are no marks on the sps from aefw.

Is this your 35-gallon cube? I would try adding another powerhead since you have them on hand anyway. See what happens. It's hard to get high turnover in small tanks without getting areas of concentrated flow that is too high or too close to the corals. I would suggest you mess around with flow a bit.

Do you use carbon or GFO or any other resins?

If your corals are brown you need more light.
