A lot of algae in qt tank. Problem?

[reefz]

The last week or so a lot of nuisance algae has been growing on the glass in my qt tank. I added a few fish today, and am unsure if the algae will cause a problem to the fishes health. The water is VERY clear, there’s just algae on the glass. Anyone know if I should be worried about the fishes health?

Mine has looked like that or worse for over a year now with no issues

Interesting how algae has been misconstrued by so many as a problem, and not a symptom of a potential issue. Algae is a good thing: it cleans up after our mistakes, the mistake usually being letting our water get too dirty with waste products like nitrates and phosphates. In a fish-only system, most algae is harmless to fish. Other than the tank probably needing a water change, you're fine.

This is true though! Thanks.

I welcome the algae, helping my tangs get through this fallow period… they love the stuff!
