curley shrimp antennae

Hey there guys, got another question. My skunk cleaner shrimp just molted and now all his antenna are curley & wavy instead of straight. Does this mean I need to add calcium to the water? The only thing I did different is I added some strontium for the first time two days ago, and I put a phosphate sponge in the filter system. He looked totally normal before he shed. Guess I picked the right one to name Forrest, LOL. Al the wierd stuff happens to that one. The other is Bubba hee hee. Thanks in advance guys.

 

I know this doesn't sound like much of anything, but I really am worried about my shrimp. I saw one at the LFS with curley antennae and when i went back 2 days later it was dead, so if you know anything about this, I would really appreciate your input.

 

I'll give you a bump as I have no idea. You might have disturbed the hardening process when you added the strontium. BTW you do test for strontium correct? Never dose what you can't test.
