Can You Eliminate This Sps Killer...

For the past 2-3 months I've been battling this KILLER that has wiped out most of my SPS colonies. Can you help me eliminate it in my 300Gal reef?
Background:
My reef has been up since 2004. I ventured into SPS a year and a half ago when I set up my Deltec skimmer. Had great success for the past year until 3 months ago.
My parameters.
SAL-1.025(refractometer), Cal=430(salifert), ALK=9DKH(ELOS), MAG=1420(salifert), NIT=0.5 to 1ppm(salifert), PHosphates=0.12 (Hanna photometer)
No light bulb, flow, salt mix changes.

Treatments so far:
Interceptor, red slime, running poly pad, and carbon 24/7 & change every 15 days, GFO 24/7 (change as needed).

So what's happening. As soon as the SPS polyp grows, a brown looking like thing (maybe brown jelly) tries to cover the polyp. Some get killed and then green hair line algae grows on it and doesn't let it go.
This is a blue tenius frag. The polyps are attacked.

From a different angle, many of them are eaten up.

The back of the coral (that sees no light) has healthy tissue.

This is my acropora nanna. Many polyps are covered by brown (maybe bacteria) stuff, others with green algae. This coral was/is growing so fast and yet new polyps get covered up quickly.

This is my ORA turquise stag, and in front of it my blue long hair mili. Both attacked but the mili is much worse.

Here is my chasterfield densis. The worst of all.

Here are some of my observations that may give you some clues:
1) Softies (leathers, GSP, candy, etc, and caps are doing fine. I have a salad plate size rose cap, and another green cap, a fireball LE, and Geng-Sy LE (sp?) all doing great, exept a monti indigo LE frag. As an example here is the rose cap.

2) I can not keep a frogspawn, or hammer alive for nothing. I just put another frag in 2 weeks ago and it already started seperating from the skeleton. (maybe brown jelly - but I see no brown jelly)

3) My milis never get good polyp extension.
4) I have a cleaner wrasse that seems like it picks on SPS polyps, but that's strange because that fish only is supposed to eat bugs. I also have a flame and coral beauty angels, purple tang, powder blue, naso, clown tang, etc.)

4) At night my SPS colonies in question seem to be "covered" by tiny/baby brittle stars (maybe irritating the coral), but are supposed to only eat diatoms.

5) I have seen some astirinas but I don't think there are enough to do this much damage.

6) My clams are doing great. Scumosa pictured.

7) I used to dose papone, but I stopped 4 months ago due to Phosphates.

8) I did the 1 day lights out with no noticable change,

9) Then I did the 2 day lights out and I noticed that the green hair line algae subsided a bit from the polyps. Within 2-3 days with normal lights it came back.

10) I do water changes twice or 3 times a week (30gal at a time). As soon as I make more water, I do a water change.

11) Equipment; DELTEC 702 skimmer, CA reactor, XL Denitrifier (no fuge), DELTEC XL phosphate reactor. Dosing KALK at night.

12) During the light period some small bubbles appear around and on the top of the green algae that covers the polyps.

If I forgot anything I'll add it as I go.
THANK YOU IN ADVANCE FOR ALL YOUR OPINIONS AND SUGGESTIONS.
 
if the green algae just keep growing on your colonies that means your colonies are dying that's all. Do u find any AEFW ?
 
I have looked very very very closely under magnifying glass, and bright flash light and have seen nothing.
I'm also thinking if it was AEFW and didn't notice them, wouln't they be eating the bottom of the colony first? All my colonies are healthy from the bottom. It's the top that gets eaten up.

I forgot to mention flow.
My return is a dart 3600gph, CL mag1800, feeder pump mag 1200, 3 Tunze nanostreams 6025s, 2 Tunze nanostreams 6055s, 2 MJmods maxijet 1200. Will add 2 more Tunze 6055s in a couple of weeks. That's about 60+ water turnover in my 300G.
 
Looks like you may have some fish nipping going on in the tank. A lot of people over look this, when it is the problem all a long. Watch the fish and make sure they are not nipping your corals.

I have not seen a fish pick on my acropora nanna. I really don't think it's that. I added no new fish in the last 4-5 months that can pick on SPS. The angles have been in there for at least 1+ years.
I'm thinking of some kind of brown bacteria that sits on the newly grown polyp and kills it.
But what can I do about that???

By the way, I do run UV (57W 16 hrs a day) and recenty just manually started turning on the ozonizer. My ORP sits at 430 to 460 so the ozonizer doesn't come on unless I manually turn it on.
 
Angels change. Some that start out "reef safe" can change their mind. I have seen flames, for example, do this.

Your phosphate needs to be about 0.04 or slightly less. Ca, ALK, Mg all seem fine.
 
dinos...what is on the substrate in the picture of the clam? have you brought in any new pieces of coral? when was the last addition? even a frag? have you dipped any of the infected pieces to see if you have flat worms?
 
I had a rusty angel for 5+ years that was reef safe all around and I started noticing a weird problem with a pollicipora. I sat back and watched the tank for a few hours and watched him picking at the polyps. Seems they can develope a taste for at any time.

I dont think this is it looking at the pictures though Id assume you have a nutrient problem. If hair algea is growing you definatly have some nutrient build up. The brown could be dinos, diatoms, cyno, w/e...

PO4 at .1 is to high. I use a hanna meter also and maintan .01-.02

The tips of the acros must be dead for hair algea to grow on them

I thought that was cyano, and that's why I did the treatment with red slime about a month ago.
It can't be dinos as they would look stringy and have bubbles upside down. correct?
I hope they're not dinos...

When was the last time you calibrated your refract WITH 35 ppt solution?
The refractometer was calibrated recently.
One thing I forgot to mention though is that I set up a calcium reactor 4 months ago and since then my PH is running low. 7.85 to 8.1. I also dose kalk at night but it doesn't raise the PH, so I'm thinking of starting to dose longer.

Prior to the calcium reactor setup I was dosing Randy's 2-part and my PH was running 8.1- 8.3.

I agree with you on the nutrient problem. Not sure how to eliminate it. If I don't feed the fish they"ll die.
When I don't feed enough my tangs get skinny. I can see their bones.
I forgot to mention that I have abour 600+ lbs of live rock in the system and pretty sure it's leaching phosphates back.

On the Hanna instrument, I don't understand how accurate the 0.01 to 0.02 reading is. The +/- error on the instrument itself is 0.04, so math says it's impossible to read 0.01 and be accurate, if you include the tolerance.

BY the way I know a lot of people claim asterina stars are harmless but I believe there are more then one type and I really feel I had a type that was eating my SPS. I just went back and reread your post and saw you mentioned mini stars, are they these?

Yes I agree these pictures are for asterinas. I have seen a few of those in my set up and pull 'em out when I can catch them.
The stars that I mentioned above are the baby brittle stars.
 
You have to use turkey baster or something to blow it see if anything fly out. However, AEFW doesn't always eat the coral from bottom.

if all the marks are at the tip, and if it happens randomly, i would say there's something eating it. However, if ALL the tips are like that, then you probalby just had an alky spike.

Also that i think your phosphate is REALLY HIGH for SPS.

Yeah I know. Your post prompted me to test my P04 just now and it came out ar .05, I thought oh no what happened so went to replace my GFO and found the pump to my reactor was cavating. So I owe you a thanks for making me want to check my P04 lol :o

I dont really have any other advice though but, good luck hope you get it sorted out.
 
Question on discovering flatworms.
Is it a fresh water dip that makes 'em fall off the colony? So far I have used magnifying glass and flash light close up but have seen nothing.

I know what you mean. 3 months ago I spent $700 on the DELTEC phosphate reactor (large unit), so I can lower my phosphates. I replace the GFO almost bi-weekly and still am fighting hi phosphates. Don't know what the solution is.
The only thing that comes to mind is the LR leaching back...
 
Im a little confused when you do your Hanna meter the reading that comes up after the 3 miniute wait is your p04 reading am i correct on that.
