ok i'll pm you in a minute here.
but i'd say for a clean up crew go for around 10-15 cerith snails. I dont like turbos..mine never do anything. But the ceriths are the best imo...just kinda slow so if you want you could prolly get like 20...but dont do it all at once. Start w/like 8, then add a few a little later, and then just keep adding till they get up to about 15. Too many and they'll starve, so if you start to notice that theres no algae or anything for them to eat, back off.
then i'd get about 5 nassarius..they'll stay in your sand pretty much.
Stay away from hermits...all mine are wearing my cerith snail shells for some reason...hmmmmmm...lol
If you want, you could add a cleaner shrimp, but they dont really clean algae, mostly just excess food on the ground, which is good, but they'll also clean your fish if they get like a parasite or something. Like the fish will swim up to it i guess and it'll grab hold the fish and start pickin away and the fish just lets him

kinda cool imo
for corals...are you getting that 36w light? if so, i'd say stick w/just some mushrooms, maybe some polyps, maybe xenias if you put them up higher in the tank...stuff like that. That lighting isnt very strong for a 10 gal hex. If you can swing it, get that 70 watt MH clip on light...that would be awsome imo, cuz MH has lots more punch in the water. If you get that, i'd say you might be able to keep almost anything..maybe not the stuff that needs crazy amount of light.
