CUC for nuisance algae

[Eatfrenchfries]

Currently have a 10 gallon display refugium on a 20 gallon mixed reef tank with a heavy NPS focus. So far I have been able to get good growth on my macros but I noticed little spots of nuisance algae on my hypnea, botryocladia, and parvispora. Is there any CUC that'll help me deal with this that won't eat all of my macro as well?
I know manual removal is ideal but sometimes I miss some spots.

@EverydayAquarist has an awesome video on this topic:

By the way, you have an absolutely beautiful refugium!

Peroxide dipping the macro frags can help. There is also dwarf snail varieties that can help.
