Hello all. I need your help. I have 11 small acro colonies in my tank. They all came in the same shipment. All Bali Aquacultured. 2 have died 1 is looking bad. And one is about 1/4 bleached. And 3 look GREAT! They are all under similer conditions. All my levers are excellent. There is plenty of flow and lighting. One (pictured) is looking like it is getting damaged not bleaching. It is going from tips down. One that died bleached from base up. I dont know what is wrong! I removed suspicious crabs and a coral beauty that was nipping it. I dont think it is my fish damaging them. Everything else in my tank looks great. The acro pictures is constantly sliming. I got these in about 3 weeks ago.

I am glad you levers are good but what about levels? we need to know

PH
Salinity
ALK
CALC
Nitrates
phosphates
Amonia
Magnisium
Flow
Lighting

SPS arn't exactly for beginners. I had trouble keeping fish alive when i started. You might want to start with softies.
 
what is your alkalinity?
what kind of flow do you have?
what size tank?
what other corals are in the tank?
what type of skimmer do you have?


the skeleton looks very green, a sign of high phosphates.
you need to provide more info to expect a helpful answer.
 
I will collect all the numbers in the morning... A long time reefer and the owner of a company that takes care of tanks for doctors and public places help me setup and is helping me take care of the tank. We just need help figuring this one out. (I will post tomorow with the exact numbers. We spent tonight testing everything we could think of. It all came back withing good limits but I didn't think to wright it down.) As for flow I have an Iwaki 70 and an Iwaki 40 and a small powerhead. One on a closed loop and one the return from my sump. There is great flow. (Its a 125) Actually to much sometimes. I have a ASM G3 Skimmer. Thanks

I edited my 2nd post to include a little more. I forgot to put that I have 3 250 W Metal Halides. They arn't all on at once. They go one at a time and overlap from one to the next for about half an hour.
 
Need params. Also, how old is your tank. If it is newer you could have some unstable params (often that way for the first 6-8 months in a new reef) that are affecting the more fragile sps corals.
 
With limited info here, I'm guessing insufficient light and skimming, and other water quality related issues - again you need to post your water parameters. Yuo levels can't be fine if you are have crolas die. You definitely do not have too much current for an SPS tank.
 
judging by the way it is sliming a lack of flow is the very least of your problems... the slime should be stringing off in the current where as in the pic the slime is webbing amongst the branches. get more powerful indirect flow, and check your Phosphate levels.
 
a g3 skimmer should be sufficient if operated properly,

what k are the 250's?

imo it's all about the flow, given that your water is suitable.
 
Interesting to see that it still has some PE while receeding.

I would throw a polyfilter in there, up your nutrient exporting, check your alk levels, and if it continues, considering an iodine with fragging.
 
If all your parameters, Lighting, and flow were good, you wouldn't be having this problem. Something is off...Your flow is definitely, IMO, too low for an SPS tank. That's only an 800 and 1500 GPH pump (not including head loss). I run a 1200 GPH pump along with two 2000 GPH stream style powerheads in my 125. I would at least double your flow. Also, how did you acclimate your corals?
 
I had time to test the phosphates before I went to classes today it was 0.1 So basicly 0. I took these pictures to illustrate how good some of them are growing. If they were all doing bad I would think that it was something to do with my levels. But since some of them are looking so good I dont get it. Unless the acros that are doing bad are expecially sensitive. I also have a video that I could send to someones email that they can look at and decide if my flow is sufficient.
The color is off in these photos because my camera sucks. But I think you get the idea. The color is stunning in real life. And look at the great polyp extention.


Yes I did add 11 colonies at once. All but 2 were supposed to be gone by now as I am just holding them for people. But things keep getting in the way of them being picked up. It is very strange because even on the ones that are looking very bad there is still good polyp extenstion in places. Which makes me think something is eating/attacking them. A bug or something

Sorry for the second post. We drip Aclimated them very slowly. Even if we had just dumped them in it seems like a problem caused by aclimation would have happened weeks ago. Also my lights are 10k
 
Have you looked at the dying colonies with a magnifying glass? It could very well be flatworms. It could really be anything. They could have been messed up before you got them for all you know.

Click to expand...

everytime ive had an acro rtn on me it had its polyps fully out, even on the tissue swinging around in the flow.
 
I definatley think you need more flow.

Ive got a 900gp return, with 2 2600gph Seios, and a 1200gph maxijet on a 110g tank.

Like stated the slime should be flowing off into the current and not webbing the coral like that.


Good Luck

Sam
 
I have put out a call to buy powerheads/ a larger pump on my local clubs site. The ones that look awesome do have a huge amount of flow.
