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.

What's your flow and turnover??

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.:sad:

What's your fish list?

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.

K sorry for the delay, coffee break is here finally. So the stock list is
6 line wrasse
2 Occ. Clowns
Bangai cardinal
Scooter blenny (dragonet)
I had a cherub angel but lost him in the tank move, he never nipped at anything though so I doubt it was him unless I just never saw it. But sps is as followsgreen birdsnest
Blue polyp birdsnest
Purple bonsaired convexa
numerous acros
salty nuts (is this an acro?)
Seems to be just the acros showing signs of little PE the salty nuts seems to have days with lots of PE and days with none. The bonsai is the only browned out one

All the corals except a few zoas and a monti frag ar in the holding tank still I plan on moving them in tonight unless I see anything on them with the magnifying glass tonight. In which case should I qt them for a few days? with a revive treatment or fw dip?

Also would a dip in coral rx kill flatworms? Or are they a little more resilient then that
