Stringy white discharge from Open Brain surface

[jsousa]

My open brain has been half closed for about a week. There is a tightly curled spaghetti-like substance being expelled from the surface(not the mouth, about an 1/2 inch from the mouth) of the coral.

My tanks parameters are more than perfect and all corals are showing great growth. I had a bit of a problem with red hair algae in the tank for the past 2 months so I reduced feeding greatly. When I was hand-feeding my corals, I was using Cyclopeeze and Coral Vibrace and the corals were loving it. I have never seen such expansion. Anyway, I stopped the feeding about 2 months ago to inhibit the algae growth but that really didn't help so I installed a refugium with Chaeto and calerpa and luckily the hair algae is almost completely gone.

Yesterday was the first day I started my hand-feeding again and I am starting to see better expansion from all corals including the brain. Stringy substance is still there though. Any ideas what this stuff may be? It seems to have subsided yesterday after the feeding but it's back again today.

BTW, I tried to suck it off gently with a baster and it seems to be connected.

Sounds like its mucus too me. A lot of different brain corals in 2-3 families produce A LOT of mucus like this. During the war between me & my false perc over its location, my Platygyra brain sent out lots of strings of the stuff. I also see it when I acclimate any other favid coral.
I wonder though, what has been stressing your corals?

I need to take a picture for you. It's not slimy at all but stringy...like Ramen noodles, very curly and very white.

As far as stressing the coral, there are Kenya trees growing very close to the brain but they have been for awhile and this is the first time I have seen the stringy substance. Also, there was red hair in the tank as I mentioned but not growing anywhere near the coral.

Let me add my params:

Current Parameters
ph 8.3-8.5
dKH 10.2-10-6
Calcium - 430
Nitrate 0
PO4 0
Temp 78 (chiller installed)

Maintenance
Daily addition of B-Ionic 2 part - 40ml each part
Weekly water change of 8 gallons
1 drop Lugol's solution added each week
6 cups Fresh water with very little Kent's pH superbuffer added daily to adjust pH of makeup(RO water I produce has a pH just under 7)

Feeding
ORA pellets for my Maroon Clown and 4 line wrasse everyday
Hand-feed Coral Vibrance and Cyclopeez 1 per week

I run a Pura pad(from Magnavore) and a bag of Chemi-pure constantly thru a Whisper 30 and I have a Remora skimmer.

Refugium is 10 gallons. I move 90-100gph thru it. It is doing wonders for the tank. Algae growth in the tank is amazing. Inches of growth per day.
