Conure beak quesiton

[ADEMIKS]

Hello everyone,
I have a green-cheeked conure and he is a year and a half old. His beak seems to be growing an under layer which protrudes a bit from the main beak. Also, I'm noticing that the edges of his beak are becoming more jagged over time. He has a cuttle bone in the cage which I replace regularly, but I'm wondering if he needs a harder substitute, like rocks or hard mineral blocks?

Recently I sanded away the edges of the tip of his beak so that I was one smooth surface, but it protruded back out in less than a week. Have a look at the picture and let me know if his beak looks normal for his age, and if he needs any special beak care.

P.S. He loves to make these loud poping/crackling noises when ever he engages in some activity--whats that mean? That he is excited?

The noises could be normal, or they could indicate an infection. His beak looks perfectly normal and it is just shedding layers.

The beak does appear a little overgrown to me... makes me wonder if he beak grinds a lot?

I agree with MonicaMc, certainly looks a bit overgrown. Perhaps one of those harder calcium perches would do the trick?
