Help! sick tank.

Last night I baffled my sump and did a 25% water change at the same time. Today my corals aren't opening up like they used to. My toadstool leather has no polyp extension and is drooping over, my purple and orange monti plate is turning yellowish, my sps had very little polyp extension and even my GSP is in hiding! My fish and inverts seem to be Ok accept for my female clown who has been suffering from a gill infection for a while now. The only thing I can think of that would cause this is that I didn't let the silicone cure long enough before using it. I used 100% pure silicon from Rona.

Should I expect some coral fatalies? What else can I do do help my tank? I do have a fairly fresh bag of carbon in the sump so I'm hoping that will help. Any advise?

How long did you wait till the water touched the silicone. If you didnt wait 24hours the silicone could have put some ammonia into the water maybe you should do a test and see if thats what it is.

Was that GE silicone I or II? Door and window stuff or kitchen and bath?

I'd crank up the skimming, do a waterchange and run carbon like there's no tomorrow.

I'm not sure what the exact brand of the silicon was, or if was GE 1 or 2. I only waited about 3 hours for the silicon to set before adding the water. I guess that was the big mistake. I'll add more carbon and check my NH4 levels and update later.

If you used normal household silcone you might want to think of reglueing whatever you did with the stuff. Normal household silicone contains chemicals that will leech into your tank over time. You need to be sure that you use aquarium safe silicone at all cost. Most aquarium stores do sell the stuff, which may be a buck or two more in cost but it's worth every penny.

Buying silicone from a fish store is paying to much for a label. There are a few safe silcones availiable from hardware stores. Most 100% silicone for construction uses is safe like GE1200 GE silcone 1 is safe and even though GE silicone 2 says not for aquariums apparnetly many people have used it with no problems. You dont want to use bath and kitchen as it has anti fungus stuff in it. i think Dannys problem is that he didnt let it cure long enough.

I've siliconed small glass brackets in my sump (for float valves and whatnot) and had it back in action within 20 minutes without any problems before. This was with All-Glass brand silicone however, so I know it is aquarium safe.

I think you may have used a silicone that contained either anti-bacterial or anti-mildew agents which is quite toxic to your tank. Carbon, water changes and heavy skimming are all you can really do for your tank now. IIRC Gunjustsuu (sp?) had a similar problem in his tank a while back.

To be honest, I've seen a tank where the overflow bulkheads were absolutely glopped with silicone to take care of a trickling leak. I'd say it was 4 hours MAX before the water level increased to start covering that silicone and then flowing through the rest of the system.. With corals.. I cringed but there were no casualties at all.
