I don't know for 100% fact that they're not bad for your tank, but I'm pretty sure they're good.
If you want to be rid of them, the best way is manual removal as you see adults

With any snail, it will reproduce as much as you allow it. You're probably feeding a little too much if the pond snail population is exploding
