Really!? A green calcium Deposit? I dunno... and a calcium deposit THAT large (it looks lilke a big lump of stuff) developed that quickly... I dunno....
Why is it "definitely not anything melted"? Are you really sure that there is no missing green plastic plants? Especially the little floating lilly type? Those heaters get hot, and even hotter when out of the water... You know, melted plastic is usually lighter in weight and a little harder than un-melted plastic... melted green plasitc is likely to end up something like a green pummice stone tinged with brown...
But, I know you don't think that is what it is... so...
Now I'm really curious as to what it really is. You MUST continue this thread untill you figure out what it is. (I'm still putting my money on melted green plastic)
Tell you what - if it is a calcium deposit, get some "CLR - Calcium Lime and Rust remover" and it should take it right off.
...BUT, Are you sure you didn't have those little floating plastic lillys in the tank? Any other small, green, plastic plants that might have gone missing. It really looks like melted green plastic to me, and green plastics objects seem to be increadible common in turtle tanks.
I'd probably try chipping at the edge of it with a window scraper no mater what it is.
