What would be better to clean this up?

My sump is starting to get a little rough and my turbos and hermits down there aren’t doing the job? What would be better? Sand sifting sea star or nassaurius snails? And if you have a better solution or clean up crew please let me know.

I might start with a quick, small gravel wash. Then I'd find some sand sifting stars and some nessarius snails.

By small gravel wash do you mean using a water change pump to suck it up?
