Sand bed corals all dying???

[kbriers]

So I have had 2 different types of coral that are supposed to be placed on the sand bed die. The first was a orange plate coral and now my open brain coral. Both of them started losing tissue from the "underside" and slowly starts to rise up the skeleton. My hammer/torch/zoas and mushroom coral are all doing great. I have noticed there are pods all over the sand bed corals after putting them in. My question is why do all my other corals that aren't on the sand bed do great and the ones on the sand die?

Lighting is a kessil 150 ocean blue over a 40 breeder. Skimmer is reef octopus 1000. I run gfo 24/7. Sg is 1.025
water parameter...
ca-500
mg-1480
dkh-9
Amm. Trites and trates all 0
phos-0
ph-7.9 (may be off need to re-cal) if not what's the best way to raise?

Sorry about all the reading I just cant seem to figure out why all "sandbed" corals die on me.

Thanks for all your help and wisdom

Were these new additions that died shortly after placing them in your tank or corals you have had for a while that started to lose tissue recently? Did sand accumulate on the corals. Guessing the answer is no, but was the flow around these corals particularly strong?

Also, did the corals have good color when added and did they maintain that color even wehn receding?

Sorry to answer your question with more questions.

Duplicate post.

They both looked great when I dipped/acclimated/placed them into the tank. They both lasted about three weeks or so before starting to lose tissue. The plate was neon orange even to the last pin head sized piece of tissue left. My brain is still neon green/pink and I just noticed tissue recession yesterday. He also used to blow up huge and the last two days I can see the ridges from the skeleton by the mouths.

As far as sand/ flow I have not seen any sand blow on either one. I have two hydor 750s that alternate with eachother.

Thanks again

Reason I asked was lighting. I have a breeder too and the shallow depth can sometimes require a bit more light acclimation. If your corals were retaining their color throughout and not bleaching then lighting doesn't sound like the issue. Flow doesn't sound too much (had similar pumps in my breeder for a while) unless the corals were close to the PH or right in their direct path. Unless you can see a pest or something picking on them I'm not sure what else to point to except those corals like to be fed. If the brain is holding on maybe shade it a little (just in case) in a low flow area and feed it small meaty foods as often as it will take it. Hope you get it figured out.

OK I will try moving him to a shaded area. I have tried feeding him but have not had any luck. Can you recommend a best way/time to try and feed. I have only seen the feeder tents. come out once and it was only 5 or six of them. Nothing like what I have seen in the pictures.

Also what food? I feed frozen brine and mysis once daily for my other critters and the occasional formula pellet.

I have not seen any pods actually eating the tissue, but I have seen quite a few around the area of tissue loss. I have also noticed most of the pods around the coral are huge. Scale wise I would say some are light colored and bigger than a dog flea and some are 2-3 times that. There are also a bunch of tiny sand grain sized ones that I can see crawling on the glass.

So last night I was trying to watch and see what maybe could be going on and I definitely can see rather large pods/ bugs all over the area of tissue loss. I cannot tell if they are eating the tissue but they are sure all over that area. Could that even be possible? And if so, what would be the best way to remove them?

I thought about a manderin, but Im not sure if a 40 breeder and 20 sump can support one long term?

Any other advice, testing etc. Would be most appreciated.

I almost said something about the pods earlier i had pods that ate my zoa, chalices and even started to eat my anemone but i took it out before they killed it but everything else would be reduced to bare skeleton or eaten until it was gone. Everyone that i told about this said i was wrong that the pods were possibly eating dead tissue but this was simply not the case i saw this all happen with my own eyes i could literally see pods eating my chalices im not sure what kind of pods they were but all i could keep was sps and clams for about 6 months until i got some interceptor to take care of them and some redbugs. Try looking at the corals at night that is when i saw the most pods eating i just used a flash light because as soon as they saw light they scattered.

I also forgot to add i had a manderin and wrasse but they could not handle these pods interceptor is the only thing that took care of them.

When you say interceptor, are you talking about the chewable dog heartworm prevention? If so what Mg. Tablet? And how do you use/dose it?

If not what is interceptor and where do you get it?
