Yes, upping your hermit population will be a help towards removing the normal hair algae...and if its long hair, help along buy pulling it our by hand...but ensure you just let it float off around the tank...
You may want to research some nitrate removal media to get the nitrate below 20ppm.....however, its not going to hurt fish at all....Documented evidence shows that fish can live happily in nitrates around 40ppm....Inverts and corals are the ones which are more succeptable to nitrates...
Hope this helps...
