Nothing better for Cyano and film algae than Stomatella snails and their population will adjust to match the food supply.  They won't touch any of the larger tougher algae though.

Banded trochus snails are one of my favourites. They can right themselves when flipped over and feed on algae, cyanobacteria and diatoms. Their pretty quick and are good at eating film algae. Also on occasion (when I start a new tank) they breed and I end up with tons of them (like in my nano right now). Usually you can find them for $3 each or so.

i picked up 30 branded trochus snails today for 60$ plus tax... not bad if you ask me... dripping them into my system as we speak
