No polyp extension

I also found that if they are not open, they are infected with some disease. Take those acros out and use reef dip, coralRX, or some treatment.

I tried that with the milli, but no luck. I dipped it in CoralRX just to make sure and nothing changed.

Any nippers in the tank like dwarf Angels?

I do have a Flameback angel, but I've never seen it touch any of my SPS.

hmmmmmmmmm...

I love flameback angels! but man, all angels nip at rock/coral, tis fact. Not saying this is why you are not getting PE on only a few SPS, but it certainly is possible.

i had absolutely no polyp extension under my t5's for around a year switched to leds and BAM growth coloration and polyp extension are incredible

I had a staghorn and a acro do that. there were no PE from day 1 of being in the tank. I found that my water was too clean. The only reason I believe this was the case was the I had a spike in phos and did some water changes prior to recieving the corals. I got my phos low and had similar readings to yours that you posted in the begining of the thread. I didnt do a water change for awhile and thats when I noticed some polyp extension. I havent changed any water for a couple of weeks and had noticed full polyp extention. I decieded to leave it alone and just monitor my levels and dose as needed. I notice that when i do a 10% water change the polyps tend to decline, but just for a short time. I know in my system that my water gets to clean due to gfo/carbon reators, filter socks, protien skimmer,ect gets cleaned to often and that removes not oly the bad but some of the good. Just my thoughts as this is what i've seen work for me.

I realized last year i was doing way too many and the volume of WC's on my 75g sps. I was changing 20g every 2 weeks and kicked it back to 15g once a month and skimmer always runs 24/7 cause i bumped ip feeding. Ive had better PE, growth, color just keeping on my dosing schedule till i can get a dosing pump. Ive also added a p04reactor and carbon within the husbandry changes. They love pristine water but still need nutrients.

I have a thinned skinned deep water acro and get no polyp extension but it is growing like crazy and the color is awesome so i know it is doing well but frustrating that i see nothing in pe..?

My tank has never had big Polyp extension. But it has been very successful during its positive phases. I get good coloration and good growth, just my corals aren't fuzzy.

The deep water acros I almost never see with polyp extension. Years ago I had a Jacquelina that had polyp extension. In the past few months I have picked up a handful of deep water acros. I have one just like Rogerwilco's photo that has turned a deep blue.

Here is when I got it

And here it was about 3 weeks later

My extension are moody - certain days i'll get them like crazy , other days i get nothing. My sps aren't dying so i'm not too worried about them. I also heard if the polyps are extending .. They are looking for food, but if the polyp are retracted, they are full.

SPS Polyp Extension, or lack thereof, is not a sign of coral health.

It could be the clean water. I have some super nice chalices that bleached out on me bc my water was to clean in my display tank....
Now that I feed heavy to get phos and not in the tank I can see the corals starting to get there color back...

Also just a random statement. Acclimation...
I had a friend hold a coral for me and I didn't realize his system was so different from mine...
His alk was 12dkh mine 9
His cal 500 mine 440
His mag 1500 mine like 1380
Hiw phos .05 mine .00
His nit .02 ish mine 0.00

So when I took my coral back it went into serious shock it took almost a month for it to have PE for me again...

Also any coral I have gotten from people that had zeovit systems have never done good for me.... Just a thought... Corals don't react we'll to fast change...

Good luck
