I knew what could happen with a sea apple.  the aquarium is my cousins and he is away in ontario for an indefinate period of time.  I am merely taking care of it.  I knew that they spewed some kind of poison out and i knew it would be fatal.  I am however thankful that the only things that were affected were the fish.  We did not have very many fish in there-mainly corals etc.  So I guess I am grateful for that.  I wish I would have known that they only affect the fish as I went crazy trying to remove whatever I could get out and fit in the buckets I had.  Yes now I am undecided on what to do with this monster.  I called the pet store today and they told me this was a "breeding" technique and that they spew them out at any given time.  They said I was lucky because none of them have ever witnessed this from a sea apple and offered to take it back and exchange it for another-or something else.
Since April we have changed tanks 5 times due to moving-setting up, buying a new tank-setting up-removing cause tank was cracked. placing in new tank-removing and placed in a larger tank.   I have not see any negative responses from this sea apple during those times.    
I now have little miss apple in a bucket waiting to decide her fate.  Thanks for the info on the heater.  For someone who knew nothing bout reef tanks I am sure learning pretty quick.
