Can you use them for anything ?

You could plant plants in them and put ramshorn, or pond snails

Come to my house tomorrow when I clean their tank and I’ll show you dirty. The leftover gunk that vacs up and the bayou smell will have you agreeing. Of course, my colony is 100+ so that makes a huge difference too!

Do you have anything else in the tank? That's not my experience although they do share with a good sized group of CPD and far too many MTS to count.
The closest I got to an issue was when I had a pebble stream running through the tank. This was a nightmare to vacuum because it was a favourite hiding place for shrimplets and used to collect uneaten food.

I know what it is. I feed twice a day and overfeed, I’m sure. The veggie sticks go down in the gravel. They’re green. That’s what I see when I vacuum.

Seems a bit harsh to brand them filthy creatures on that basis

Well, many call my goldfish filthy too and they certainly can’t Help that they have a large bio load. I’m very sorry if I offended you. I read an article that said the reason shrimp bottoms get so “nasty” (that’s what they called it) is because they ground their food down to such tiny pieces that it easily builds up in the substrate. See, I’m not the only one. I love my shrimp but the tank gets nasty. Fact of life. I love my kids but when they were small they often got nasty too.
