Grey/white Round Spots On My Valisneria (Jungle Val) .

[Fish bubbles]

Hey people
 
     I see that i have multiple grey or white looking rounded, humped spots on my val and no where else in the tank. They have been there for a week or two and haven't grown or moved as i thought they could have been tiny snails. They do look similar to a lake or river limpet. If i can ill add a picture tomorrow.
 
Any other guesses?
