Macroalgae clean up crew?

[caveman28]

Hello everyone, as the title states i'm looking for a clean up crew that'll be safe with macroalgaes in a 20 gallon
so far i have red grape algae, gracilaria hayi, feather caulerpa, caulerpa prolifera, and some augophyllum wysorii. i plan to have like 1 or 2 soft corals along with those macros but i havent decided what yet.
I'm open to any suggestions and advice!

Snails & small Blue Leg hermits crabs are good options. I like Green Star Polyps & Xenia for soft corals.

I have snails and hermits in my macro algae tank, and some mushrooms. I also added an aquaman monti, I'm hoping to encrust my entire rockwork in it.

Noted. I was hesitant with adding hermits because i kept getting conflicting info regarding their compatibility with macroalgae. Is it mainly just blue legs that are safe for macros crabwise?
Also What kind of snails? I've Heard some cant flip themselves over and i wouldnt want a snail to die like that and start spiking ammonia.
Also what about sifting the sand or turning over the sandbed to aerate it?
And last question, will any shrimp actually help in cleaning or are they mainly just pretty to have in the tank?
I personally dont want xenia or GSP as i'd rather not have them cover everything even if GSP is absolutely beautiful.
Sorry for the question spam lol, i want all the information i can get

Most smaller hermits are totally safe with macro, once you get into the larger ones (Halloween, thin stripe) you test your luck a bit. I personally love dwarf ceriths and regular ceriths as my main snail population (the dwarfs can actually climb on the macros to clean them) with one or two trochus snails to get the real gritty stuff. All three species can flip themselves over.

Shrimp are awesome, but don't do too much for algae usually.
