Uneven Shell Growth

HI everyone, back again with yet another dilemma. I've noticed this for a little while now but thought it would be healed or fix itself up. My mystery snails are all growing and thriving yet there seems to be 2-3 of them that are growing a wonky layered/peeling shell. Not sure why it's only happening to these 3 because the rest have a nice even smooth growth. I have bits of eggshell in the aquarium, which are the white dots on the substrate, as well as a wonder shell and a cuttle bone. Anyone have any ideas? Might it be old age? Please help );

 

How often are you doing water changes and what are your water parameters? Shell problems very frequently occur because of bad water or inadequate nutrients. Mystery snails produce a huge amount of waste and in a tank full of mystery snails AND goldfish (as it appears yours is), you probably need to be doing at least 2-50% water changes a week. Make sure your snails get plenty of calcium, a protein source, and enough algae and plant source foods.

I do 2 40% water changes every 3 days. My tank is pretty clean, what I find weird is that out of my 13 snails only 3 are growing funny. I have a wonder shell, cuttle bone and eggshells in the tank. Plus I just bought calcium carbonate which I plan to include. I feed them bloodworms, brine shrimp, zucchini, algae wafers and a calcium/veggie pellet mix I ordered off of S&C aquatics. This one also has a wonky antenna. I really don't know what else it could be

 

what's the GH/KH of your tank?

I haven't been able to test for that, I do not own those testing kits, I only have the regular apI freshwater kit. I need to go out and purchase them ASAP ):
