You should probably get more snails and hermits. I'd do like 15 more snails and 5-10 more hermits. They'll help keep everything cleaner and hopefully once you get the cyano under control they can help to fight it coming back. As for types, Astrea snails are really good cleaners but I really like the Ceriths and Nassarius for their sand sifting efficiency and Nassarius are fast little guys that really pull their weight and then some. For the hermits, I'm partial to the scarlets.
