snail selection?

[niloc16]

i currently have a 55gallon that i have been battling with hair algae and bubble algae. i've tested everything with no luck in finding problem. i upgraded prizm skimmer to remora aqua c, and man what a difference in skimming but anyway, diatoms have definitely slowed with addition of new skimmer and its only been a week but to me it seems that the hair algae definitely slowed down. my question is herbivores, i have 12 astraea and 2 trochus snails currently, from research i've decided on getting some cerith, bumble bee, and nassarius snails to clean detritus and algae. i was wanting your input good or bad or experience with these snails to know if they will do the job. i dont have anything right now to clean detritus, and i'm really hesitant to get hermit crabs because i dont want the killing the snails i have, i tried a sea hare but it died a week after having it for no apparent reason.
