Hi and welcome to the board! If your lights have shifted spectrum in the year you've had them, they could contribute to your algae problem. Just one possible factor, there's also a thread in the Reefs forum now asking these same questions.

Do you have more details regarding your system - filtration, skimmer, circulation, bioload, rock, substrate, etc?

Also what's your snail/hermit crab population like?

Maybe cut the photo period down by a couple of hours until it's under control.

I have 2 snails and no hermit crabs in a 270G and previously in a 300G and never had a hair algae problem ... too many nutrients and detritus buildup has always been my guess as far as hair algae goes ... my cousin in JA had a outdoor saltwater pond and huge hair algae problems and he had natural sunlight so I am disinclined to think spectrum alone contributed to it although it may be a contributing factor. The only nuissance algae I have had is valonia and I have no clue how I got it but it never got to plague proportions ( would find one behind a rock or something if I was fooling around in the tank :rolleyes: )

Maybe you can rent Albert's sea hare after its done cleaning up may hair algea problem. :biggrin:

I have a question for you, do you use RO water or conditioned tap water? I have a theory about Calgary water in the winter and PO4 levels.

Danny ,

You can request a water faq from the City, there Seems to be more of a difference during the Spring due to the run off I have an old copy around somewhere I should dig it up.

You can't forget the ammount of algae eating fish you have Steve.
That would/could account for a huge diffrence in his tank compared to yours.

But Tomini doesn't like to tell us how many he has anyway :razz:

I've heard that this can actually spread the algae diatoms around. :question:
