I'm sort of wondering if it could be bacterial. Sort of like the brown jelly that usually attacks Euphyllia? But I have no idea, just a grasp on my part.

FWIW, I run my SG at 1.025 and temperature I try to keep at 26C (about 78-79F I think? If I have my conversions straight).

It is pretty uniformly SPS across the board. Softies, LPS (well, actually, I don't have many LPS. But I do have a bubble coral, and two Blastomussa's), anemones, and clams don't seem to be an issue.

This is now spanning two different systems. But one thing the two systems have in common are some rather large anemones. Two gigantea carpets in one tank, and one ridiculous ritteri in the other. It feels a bit of a desperate grasp though, to me, as there are tanks out there with these species with SPS that seem to do well.

I'm no expert on sps but... My tank is mainly dominated by softies but I do have a few lps and sps that seem to be doing quite well. Do you run carbon or phosphate remover of any kind? I believe carbon and even phosphate removers can help remove organic toxins. Ialways try to have atleast some carbonin my tank.(thats actually the only mechanical filteration I use) I know that softies can excrete a fair bit of toxins which can be potentially harmful to sps. Sorry I can't offer anything else.

How would you be able to determine if you had such an invader in your tank? I wonder if you could send a water and sand/rock sample to a lab for analysis? You know, someone who knows what to look for.

I have ventured into a few sps .Some do good/some turn brown some die.Asked Jaws about this and said luck of the draw so I dont think it is anything you do.

A few potential causes (I fought off sleep and read through several gargantuan threads on RC!):

1) High (organic) phosphates?
2) New house, new area, new water source/water treatment plant? Some use Chloramine?
3) Salt mix. Did you switch salt mixes? I just read that some salt brands are using many times the natural amount of Borate in order to keep the mix in solution. As I understood/read it, high levels of Borate skew test readings for Alkalinity (ie. the true dKH will be much lower).

Try adding some poly-filter... supposed to absorb a wide variety of stuff. Might help...

The water thought occured to me too. But wouldn't RO/DI deal with chloramine if it was present?

Interesting about the borate/alkalinity connection .. hmmmm, will have to do some reading on that one. I'm right now using a bucket of Kent, was using IO before that. I've sort of bounced between IO and Kent over the years.

I have run carbon off and on. When I do run it, I have a small amount in a Phosban reactor and try to change it out every week or two. Also, same with the Phosban, I do have some on right now. I'm not sure how to tell when it's time to change it out. People say they change it out when their phosphate levels start going up, I have yet to detect an upward trend when I test PO4. I'm never sure if this means PO4 is OK, or just if my test methods are inadequate. Maybe it's time to buck up and pay a lab to do a chemical workup, if for no other reason than I can maybe express some confidence in the #'s I do come up with.

It should deal with it.....but how old are your filters? And what type of carbon filter do you have on there? I've read about the difference between catalytic carbon vs. granular activated carbon (the former being better for chloramine removal).

Just some thoughts....maybe it's your RO/DI filters?

I'm no expert, not even close, but it really blows my mind that you can keep some really nice clams happy and healthy but you have problems with SPS. Is that little cube you have with the carpets plumbed into the same tank?

Delphinus · #10 12-10-2007, 02:07 PM

Hi Greg, it is plumbed together.

This coral in particular though went into my ritteri tank which isn't plumbed into that system. But there's enough transfer back and forth (feeding, or moving a coral over from one tank to another) that if it was, say a pathogen such as a protozoa or a bacteria that it couldn't just hitchhike over and "infect" the other tank. (I hope I'm way off base on this theory though.)
