Sunlight or No Sunlight

The only things that I found that promote algea growth are a clean place for it to grow and excess nutrients. Nearly any surface in a marine environment will be a suitable place for algea to grow. Just look inside the pipes used for the plumbing on your tank. Those places get no light. The rate at which algea grows is goverened largly by the amount of free "food" in the water for it to consume. Take the "food" out of the equation and you have slower growing algea even in direct sun.

the algae in my tank grow on the side that doesn't get direct sunlight what is up with that!

i use the natural sun in the morning b4 the lights turn on to help the corals wake up b4 the halides go on its my first light cycle
9-9 natural sun well in summer atm its 9-5
10-10 halides 12k

I was @ Ohios biggest marine aquarium shop last week and they have the whole front room in a greenhouse and huge, shallow tanks they are using for fragging. They had a couple of antinic lights on but mostly working on sunlight. It was an amazing setup. That said, I have a spot on my tank that sun only hits in the winter and i have brown diatoms showing up lightly on that spot and glass. Nothing huge, just needs cleaning.

My tank receives indirect sunlight. It's good for the corals growing on the sides of the tank.
