I dont't think so.
As far as I know and from what I have read it sould not have any affect on it.
However, the higher SG the easier it is for parasites to live and bloom/ reproduce.
How much higher are you talking anyway? and higher compared to what?

i've read lower SG can contribute to algal blooms.

well a guy at the LFS keeps his fowlr tanks at 1.017 because he said it helps control algae and parasites...just curious if theres any truth to what he's saying...so high would be 1.026 which i know isnt high but apparently it is to him

Lower or higher salinity wont affect algae growth. Phosphates,Nitrate overfeeding, lighting will effect alage growth.

Lower salinity will help with parasites such as ich, but 1.017 wont do anythign to parasites, you have to lower the salinity to 1.007 to have any effect on them.

I don't think salinity has anything to do with algea blooms. It's nitrates, phospates, and death that promotes growth.

Twenty years ago, I was told to keep tanks at 1.017 for corals. Less salinty promoted coral growth. Yes, they were very puffy.

No matter what, algea is a problem with nutrient rich tanks.

Skim wet, skim often, grow macro algea, and an RSB is a good idea. Bare bottom and lots of flow helps too.

BTW. If you can't skim anymore, a little bit of sugar make the skimmer work better. Don't ask how I know.
