maxima dieing

I have a 1.5-2" maxima that looks pretty dead. I went away for a weekend and when I came back the poor thing was open with it's tissue slid down in the shell, the mouth looked like a hole instead of a slit and I thought it was dead. I went to pick it up and get it out of the tank and it did close up so it's still alive. I have done regular feeding with DT's (every other day) and it's been sitting under a 250w DE metal halide. There are no fish in this tank and I haven't seen any hermits or other animals bother it. Is there anything I can do to attempt to save him? Would a freshwater dip help possibly?
 
Sounds like a gonner. I'm very sorry. Your light and feeding sound fine. And with non fish that eliminates another possibility.

Let's figure out what happened so you can get another. How old is the tank? What are the current chemistry readings and how did you measure them? Lastly, did you check for pyramid snails?
 
Yeah...gotta agree with Peabody, definitely check your parameters...especially after being gone for a weekend, the salinity may have shot through the roof if there was no topoff being done. Or there may have been some other die-off that is causing a cycle to occur in the tank. Check your water, do water changes if you need to to get back to baseline.

And freshwater dip...I wouldn't recommend it since it's just gonna stress the clam even more. I'll keep my fingers crossed for your baby clam...hope it pulls through.
 
Params seem ok for what I have tests for.
80 F
1.024 SG
Ammonia=0
Nitrites=0
Nitrates=0-2.5ppm
Cal=380
Alk=3
I do have some green hair algae so I have to assume there is phosphate in the system. I've been doing some 10% water changes every few days with oceanic salt and it seems like the hair algae has gotten worse which is odd because there are no fish in the tank. Any ideas or suggestions?
 
CA and ALk are a little on the low side, but not dangerously so. How are you testing SG?

How long has the tank ben set up?
 
algae getting worse with water changes + no fish in system = unknown source of phosphate???

Any other sources of organic input? feeding heavily for the corals? Another possibility is the water you are using to mix the salt...RO? RO/DI? Tap? check your fresh water source to make sure it's clean. Last thing to check would be your salt mix...sometimes there are bad batches.
 
I'm not feeding mcuh with the exception of the clam which gets DT's every other day. I have a 6 stage RO/DI system but I will pick up a TDS meter today and test that. I'm also going to switch to instant ocean for salt as I've heard some negative things about oceanic. Any advise on how to clean out the phosphate currently in the system?
 
well...I've used IO salt for the past 3 months and things seem to do ok...nothing bad yet. But IO is really low in Mg and Ca, so be prepared to dose supplements.

If you have an RO/DI, then phos shouldn't be a problem...unless your membrane and DI filter is old and needs to be flushed and replaced, respectively. If the phos truely is high, then I'd do more frequent water canges with water that you know is phos free. For your 55G, I'd go 10G each week for 4 weeks straight so you almost replaced the entire tank volume in one month.

You could try using a Phosphate remover (Phosban/Rowaphos). I understand that there are varying opinions on the use of these products. It seems the fast drop in Phosphate levels can have a negative effect on SPS coral. I have been using it consistently from setup with no negative effects, but I do change it out more frequently than recommended. These products do reduce the phosphate levels pretty quick.
