Swollen acro flesh?

[JSeymour]

So I just was looking at my new setup, the 45, and noticed a couple of my acroporas have swollen tissues and polyps. Look like healthy lps flesh. Not both on any one acro though. Not all acros are affected. They appear fine otherwise. I'll start testing in a second, just looking for some early responses. Parameters and pics in a hour or so(titration, ugh).

I don't have a fix it answer for you unfortunately, but I have seen what your describing on one of my SPS. Eventually the "bubbles" went away and I haven't seen them since.

Parameters tested so far. Drip, drip, drip...

Salinity- 1.025
Calcium- 415 ppm
Alk- 7.7 dkh(day time)

I'll be dripping kalk in a few minutes.

Pics(camera phone, cropped and enlarged).

See swollen polyp on far right.

Hard to see, but see the "bubbling" on the rear tips.

Only things new, i just upped my vodka(+.25 mL/day) in this tank(would expect the opposite though) and treated for redbugs about two weeks ago.

Back to testing...

More results.

Magnesium- 1230 ppm
Temp- 81 F
Nitrate- undetectable
Phosphate- undectectable
Lighting- 6 hour photoperiod with 2x250 mh 14k, 18 white and blue LEDs and 10w t5 20000k for viewing other 6 hours before and after(staggered on/off).
2 mL of vodka daily, just increased .25/day yesterday, 60 mL vinegar nightly(mixed with two teaspoons kalk per gallon, my standard practice for years).

I'll check my alk in the morning too to check day/night swing, but it's been less than .25 dkh so far(drip kalk at night).

All test kits are salifert. I'll see about borrowing a hanna phosphate meter, but I don't know anyone that has one. I'll have to make some calls.

The newest addition was added when all the others(frags from corals I've had for along time) were added, about 2 weeks ago, an ORA Frogskin, direct from ORA into my tank.

Changed my small bag of carbon that I run passively, just in case of some contaminate. Water change day is Saturday. Unless it's felt strongly I do so, no plans to do it early.

Like I said otherwise they look great, growing and coloring up.

I'm at a loss, maybe it's nothing, idk.

usually happens when they try to close up to fast and thats the excess water in them it will slowly go down or maybey it had its polpys out and the flow changed and got hit real hard and scared it.

Alk this morning- 7.55 dkh

It doesn't appear to be spreading, getting worse, or anything negative really, but it has only been 12 hours. They did shrink up slightly at night.

Didn't mention earlier, have two fish fed 3-5 times daily. One is a yellow longnose butterfly, but I don't think it's the problem. If anything, I would expect the complete opposite reaction. I also, personally conditioned this fish at work in our sps frag tank for a month. He's not a nipper.

 

[john90009]

well alk could be up id say a easily kept range is 9 that was when it goes low it doesnt hurt anyhting. 7.55 is low.

 

[JSeymour]

Recommended carbon dosing alk is 7-8, as close to NSW as possible. Any higher and your sps tips will burn.
This is also the lowest it gets, before lights are on. Last night before the lights turned out, it was 7.7 via salifert. That's pretty stable. I know how to titrate properly, it's not user error.

oops didnt know that sorry if you stated it above i dont read much lol. just keep watching the polpys , if a fish was nipping the polpy wouldnt be there or have chunks missing so i wouldn't think its the fish either. mine do it when there polpys are out and i get near it or swoosh a alot of water at it and it retracts so fast they swell.
