Possible saltwater issue Edmonton area

[Skimmin]

Over the last few weeks I've been noticing a small amount of brown algae and a sort of clear/white 'fuzz' growing on my powerheads and on a few spots of my live rock. Just wondering if anyone else has had any of these issues? I don't use R/O but never have, and this is the first time I have ever had any kind of a algae/bacteria issue. Any insight would be helpful.
Thanks

I haven't noticed anything yet and I'm on city water & don't use an RO either.

Yep ....I use ro di water happens. Just pick it off you eventually win. Some time if they get large enough they just float off and you can grab them then. I had an epsiode and it took about a couple of months to get rid of them.....They love to attach to staghorns
