I think his tank is larger then ten gallons. Lol I have a nano tank it 28gallons. I have 1 large turbo snail, 2 zebra snails, about 4 hermits, and 1 cleaner shrimp. I had a emerald crab but he started to eat my corals so I took him out. I also have like a hundred nassarius snails because they breed but I agree one of the neatest things in the tank.
In a ten gallon I would Probaly go with 2 hermits, 2 snails, your choice on the kind, 3-4 nassarius, 1 cleaner shrimp. Ya don't want to start with to many so if you find that they arnt keeping up with tidying up you could add one or two more. My rule of thumb has always been they eat and poop as well they will grow. I started with 6 hermits and two have died off or were killed.
As far as cycling I used the table shrimp method took about three weeks then I added my cuc. Waited another 20-30 days for them to clean up the algae then added my first two fish. Clowns.
time and patience are the best in saltwater and as long as you stick with the pwc
every week you shouldn't have to worry about any build up of nutrients. Wow that was long. Glad to see someone so excited about starting up. Good luck and ask questions as they come to ya.
