I've read several times now today that too little lighting can produce certain strains of algae especially brown algae. I've always restricted my lighting to about 6 hours a day. Does this statement have any truth to it? I am battling algae at the moment, but I never considered too little lighting could be an issue. Can anyone provide any experience on this topic? I always assumed algae growth meant too much excess nutrients.
Does too little lighting promote algae?

Algae need light and nutrients. Matter of fact, a great way to knock it back is to go dark for 2 to 3 days. Turn the lights off and drape some towels over it. No need to seal everything up or worry about a little light getting in when you feed (lightly!) During that time.

I've never heard that idea expressed and I believe it to be wrong. But that's an opinion, not a statement of fact!
Some people do lights out totally for 3 days to reduce algae. I've done just blue leds for a week and got rid of algae and still had coral s and anemones open up and look normal. And under the blue leds got wonderful color fluorescence as a by product!
