Keeping my Refugium Cleaner?

[Eb0la11]

Hey guys,

so Ive had my refugium set up for a good 2-3 months now and it seems to be getting dirtier and dirtier because of the low flow format of it, which helps with my DSB.

Is there something or someway I can clean it? Its even starting to show cyano which is no where else in my 165G DT. Is there a critter I can put in there to clean it?

Also should I scrape the glass much in there? There are a ton of feather type dusters on the glass growing that Id like to remove, is that bad to do?
