I have a favia that appears real ****ed. I moved an acan that was next to it, and it is getting more direct light now, which it appears not to like.

I also have a couple acros that seem to have a brown slime developed on the tips of some branches. They have lots of flow directed at them. It's not on all my SPS, but just a couple pieces. The Myagi Tort is one of them, however, and it had just started to color up nice. It also appears to have white stringy things coming out of it at night. Anyone have any idea on what causes this in acros? I need to do some parameter testing. I changed my GFO after I saw the issue because I was getting algae on the tank again and thought maybe my phosphates had crept up. I'll also be monitoring for temp swings. I'm thinking of doing an Arduino controller to help monitor and maintain levels.

Then this morning I saw that my crocea clam was super ****ed. Took a closer look and it was COVERED in pyramid snails. I havn't introduced much to my tank in a while (and no clams), so I don't know where these came from. At least I had an excuse to finally cut it off the rock it was on, which seemed to go just fine. I screped all the snails off, but I'm going to be keeping a very close eye on my Maxima and Squamosa too.

Awesome.....
 
This sux. Sorry to hear, esp with your coral acquisitions. Too much light on the brown outs and parameters on the algae. I do get the white strings in my acro's after feeding and not to be confused with polyps.
 
Ok lets deal with one problem at a time.

The Acan can sting the favia so keep them far apart. But I think it was already stressed.

Brown sline/burned tips pn acros points to most likely alk swing. and alk swing is related to your dosing, BFO, low magnesium, ect. So get your alk and related parameter in check and the scros will come back.

pyramid snails and clams ... thats a tougher one, you will have to hunt down and get rid of them manually, some fishes (wrasse) do eat it but it is hit and miss. I think if your clam was healthy it might not have been killed so quickly by the snails. So your main problem is the tank parameter contributed to all three problems. Fix that first.
 
The favia was fine before I moved the acan, but the acan was shading it. It's in more direct light now.

I had figured an alk swing was probably the culprit. I'm going to need to start testing/dosing.

The clam is still alive. I did a water change this morning, removed it from the rock and tooth-brushed it off. The mantle was partially out by the time I left for work, so I have strong hopes that it will live. I'll probably have to do a few more manual removals, but it isn't tha mig of a deal.
 
Sounds like the guys pretty much covered the bases Ben. Biggest thing I would say is get the params back in line. What do you use for dosing?
 
Hey James, didn't see your reply here. I've never seen red bugs. I'm assuming they would be self explanatory if I saw them. Are they out most of them time or do I need to do some search for them. The Myagi still has brown slime on some of the tips. It isn't loss of color, more like dying tissue if I had to guess. It isn't getting worse, but it isn't getting too much better. I still haven't tested my params (I'm generally very slack about this), so I'd have to point the finger at me rather than at a pest. Just a hunch though. My Tyree Vercussa* is basically in the same spot in the tank and is look great. Really coloring up, and has about tripled in size with the new tank. Same with my green slimer that is near by. When my last tank was on its way out, the slimer massivley RTN'ed. It was about 4" tall, and I fragged 1" off the end to bring to the new tank. It has encrusted a large area around where I mounted it since getting into the new tank.

As for the clam, the Crocea seems to be doing very well. It has large white regions at the edge of its mantle, where I am assuming the pyramid snails consumed the zooxanthellae. Hoping it colors up again. The mantle is fully out and looking good except the color. I prefer its new location since I cut it off the rock too, so maybe this is a net win. I saw one snail on my Maxima, which I promptly removed. I'll be monitoring and removing for a while. I think that's about all I can do. I was planning to get rid of the Crocea at some point, but I suppose I'll need to hold it for a while now so that I can ensure it doesn't have pests and is healthy.



* spell check?
 
Grant: I don't does at all. I'd need to be much better about testing to get that going. I plan on adding a controller and dosing down the line possibly. I do have some bIonic two part that I can use. Maybe I'll do an Alk/Ca test tonight.
 
Check your levels. I'd bet you are at if not now past the point of needing to dose. Plus if you haven't been monitoring your magnesium, it's probably low, which can make elevating your alkalinity more difficult.
 
my experience is very limited but even though all of my corals are small i can see my calcium and alk drop daily if i dont dose a little of each.
