Receding/Pissed off acan lords

My rainbow acans have been "sucked in" for probably a month now, not looking real unhealthy, just not happy and super puffy like my acans always are. Now one side is looking like it is possibly receding/bleaching, other side looks slightly better?! I moved them down to the bottom of the tank about a week ago, thinking maybe it was the light, we upgraded fixtures from 70-150 watt but that was at least 3 months ago now so I expected it was fine. The tank is just getting over my brown algea issue but nothing else seemed affected and everything looks great, except those acans. I dipped them in some reef dip/iodine stuff we have sitting around (don't remember the brand off hand) tonight during water changes and moved them to a different bottom corner. Anything else I can try? Really don't want to lose them.

What is your PH?

I'll have to break out a test kit tomorrow or recalibrate my ph tester as it's off, I tested everything a few weeks back because of the algea and everything was within range except alk was slightly low. I'm bad, I test about 3 times a year now.

The reason that I ask is that the PH in the aquarium at the science center is running a little low, and a bunch of the LPS doesn't seem to like it.

Well I ended up cleaning house and then didn't want to stick my chemical covered hands in the tank so hopefully tomorrow I can get around to testing, I "think" they looked slightly better today though, I might dip them again tomorrow.

Update, this frag has been doing better since placed in a shaded area, started puffing up slightly and putting out feeders, I moved it a little more under the light today hoping to slowly acclimate it back somewhere I can actually see it.

However, another acan frag, which has been sunken in like the receded one is having issues, part of the skeleton is showing, it was facing the back of the tank so I didn't notice, turned it around to hopefully figure out what's up and might end up dipping and lowering in the tank as well.

well what i think it is they need to be at the bottom for a month or so, because thats what happend to mine so i put it at the bottom and still is and its doing great some acans dont need much light as others!

Have you changed anything else besides the lights? I'm having a hard time finding a place where mine are happy since I moved the powerheads around.

Seems odd having you post that your acans are ticked and even receding . You're the acan queen!

I know right?? All the rest as happy as can be. This colony that's having issues now doesn't look bad from the front, but there's a spot in the back middle where you can see skeleton and some flesh hanging off, that's how I noticed something was off. Powerheads have been moved and moved again but doesn't seem to be the issue. These have faded out in color as well, not bleached, just duller looking. I'll try the same treatment as the last frag and hope it works again.

Sounds like it worked last time so may as well give a shot again. Have you done any testing yet? I'm curious if you find anything there. Color fading sure sounds like it could be the lights too though, huh?

I tested everything a while back because of the algea and nothing was way off, everything else in the tank is doing great, clam is growing, coralline is growing all over (finally!). Even the two other acan lord frags look fantastic. I dipped both problem frags last night and they are on the bottom of the tank so I'm crossing my fingers they look ok today, they were pretty mad about the dip.

Last update, the acans are still on the bottom of the tank but in the middle and are looking a ton better, I am going to start slowly moving them back up the rockwork but I think we are in the clear.

Speaking of PH do you all Kalkwasser? Do you dope? If so what and what quantity. Garrett should this be a separate post? Can we talk about this at the meeting tomorrow. My PH was okay but my KH was low. I began a manual doping of Kalk one Table spoon per day, dosed at evening after the lights went out, and a Tablespoon of soda mix per recipes on RC. (small 29g tank) My PH was ok at 8.2 but my KH was 6-7 funny because after a couple weeks on this regimne, my PH is 8.0 but my KH is now climbing and is a solid 8. I have wanted to ask this question for a while, now that I understand the why and how of doping a little better.

we can talk about this at the meeting. Meeting is sunday though but if you wanted to come tomorrow i will be around as well.
I run a calcium reactor all day,
kalk reactor at night
quad dosing pump
the neat part is that from my iphone you will be able to look at graphs up to a month progression of all my phs, temps, orp, conductivity and a bunch of other neat stuff.
If you are interested in knowing quantities and such i will be able to tell you exactly how many ml every hour and stuff like that.

Probably would be a good post for it's own thread.
