IME perlite actually tends to float to the top because it's lighter than the rest of the soil...
Why do you want to add more perlite? Most folks use it because it's basically inert, i.e. contains no nutritional value, and doesn't break down easily.

just mix 25-30% perlite to your soil when transplanting..so 2 cups soil 1 cup perlite, or 3 cups soil, 1 cup perlite.

When I run out of coco I top fill using perlite that is leftover from my failed trial with Autopots. Plant loves it.

I always thought perlite was to help drainage.
That's what I always thought. Perlite to help not retain water and Vermiculite to retain water.
So if it's a too wet soil mixing Perlite can help. If it's a dry soil Vermiculite can help.
Both are basically popped rocks so what nutrients I cannot say. None possibly,
I recently bought organic soil from an organic soil store (believe it or not) and they had Gypsum in the mix.

Then there is Vermiculite.
What is vermiculite used for?
How to use vermiculite. Vermiculite helps to aerate soil while simultaneously retaining water and nutrients, which it then releases over time. Vermiculite is therefore useful in seed sowing and propagation. It can also be added to house plant compost.Feb 26, 2021

Also from another article
Once I have recycle all my soil through composting I will be adding Gypsum for next winter's grow.

Perlite stops compaction for me. I use large containers with coco. Unorthodox but it works for me and my lifestyle. Coco doesn't need perlite for aeration. It's a good "foundation".

Wisdom in every word.
I love reading what people do and think with growing.
Never tried Coco. I read good things about it.

Talking of coco, is it beneficial to mix it with soil for grow bags

Coco holds as much oxygen as moisture from what I understand. I used to run Sunshine Advanced #4 bales and they had coco in them. If you feed plain water and add coco to your blends make sure to add some calmag for your first few waterings, it has a natural tendency to absorb positive ions.
