Higher alkalinity = less algae?

[Charley]

Just wondering if a higher alkalinity tank (9.5 dkh or higher for example) would be significantly less prone than a lower alkalinity tank for algae to grow or to take hold?

My alk has been sitting consistently at 11 and I get algae like crazy!! I clean the glass 3 times a week

Was hoping this would be a more hostile environment to algae.....is there such a thing?

I think you are thinking of higher magnesium, and that was mostly due to an impurity of kent's magnesium addititive which is no longer made in that way. Also I keep my alk at about 7.5 and have no algae issues at all

There’s many different kinds of nuisance algae that can cause problems in the reef aquarium and Bryopsis can be one of the worst, or one of the ‘best’ depending on your perspective.

Do not have bryopsis......just good old hair algae. So it seems like high magnesium is the only deterrent to GHA maybe.
