Default Why are snails turning white?

I have a lot of MTS's and Ramshorn snails that are turning white! I've never seen this happen before. It seems like it has started with in the last month or less since my last re-scape of the tank.
Here is a ramshorn

and one of an MTS


could this just be from old age? or some sort of deficiency.
Also I have alot of old dead snail shells in my tank. From loach lunches or old age. If these accumilated would they eventually start to harden my water and raise my pH. I know your not suppose to put decorative real shells in your tank for that reason.

I think there shells turn white when the hardness is too low for them. I am not a snail expert but I remeber reading this somewhere that they turn white and then break killing the snail.

Lack of calcium from what I have heard. However my hardness is 16 and my snail shells still turn white.

I took the liberty of fixing the images. What you did was link the page they are on. What you need to do is right click on the image and select "Copy Image Location" and use that as the link.

I think it is when they turn clearish white and brittle that they are lacking calcium. I have some that look like yours as well, not sure if it is old age or perhaps even a disease? I've even wondered if it is places there the snail's shell got damaged somehow (fish?). If your ph is close to or below 6, however, that also can be a reason.

oops sorry, thanks for fixing that.
When I right clicked on the pic it wasn't one of the options.

When the snails get old, their shells begin to erode, especially if CO2 levels are high. There is a brownish protective covering on their shell, and if that gets scratched, scarred, or just wears out, then the calcium carbonate underneath begins to dissolve. Rapdily growing snails, with plenty of food do not show this.

Hi
I have the exact same snails in GH of 0.25 and pH of 4.0 and they look healthy. Maybe you need to feed them, is there some food for them?
