What size clean up crew is recommended for a 75g reef tank?

Depends on what is currently in there. If you have any predators such as a puffer fish in there then it's really hard to have any sort of cleanup crew. My valentini is relentless when it comes to eating snails.

But, if predatory fish are not a problem then you can go with the 1 snail/crab per 1.5-2 gallon - depending on their size and type. You always want a detritus cleaning crew, algae crew, and filament/hair algae crew.

The only thing I have in my tank right now is a lawn mower blenny, and a chromis as far as fish go. I also have ten trochus, 1 turbo and about 6-7 hermit crabs and an emerald. Oh yeah my tank just went through a cycle and now I have a bad diatom bloom in the sand bed and live rock.

So you have roughly 17-18ish actual CUC other than the Blenny. I would add 29 more Turbos or margaritas, 10 more trochus, 20 nassarius for the detritus, and about 30-50 more hermits and see how it works out from there.
