Newbie algae question

Hello everyone!

I am very new to the saltwater hobby. I have a 30 gallon jbj tank that I have just put clowns into a week ago. I have 4 key red hermit crabs in there, 2 blue legged hermit crabs, and 6 margarita snails. I had 4 blue legged and 8 snails, but the 2 hermit crabs disappeared and two snails were eaten by the red hermit crabs early on. No carnage since then.

Recently, I have had a large algae outburst (before I even got my clowns). It was brown algae for a few days, then that went away. It is now green algae, that has been spreading and getting denser on my rocks daily. I got an algae scraper and cleaned the glass, but am wondering what I should do in order to stop the spread, and have it go away?

Nothing so far has been going really wrong. There were some zoas on a live rock I had used in initial set up that have been growing like crazy, and they are doing fine, and clean up crew is trying just to pick away at it. Nitrates at close to 0, 5 0r 10 max using API scale.

Should I increase my clean up crew? I started out small, in order not to starve them while nothing else was alive in the tank.

I believe I leave the lights on too long, also. I have them on for 10-13 hours a day, on a preset cycle. So, it is not on full percent all day, but is rather tame in terms of intensity in my opinion. I am willing to do a custom lighting setting cycle on my orion light, but in order to prevent algae growth I would like to know what you guys think my max intensity should be in percent of white and blue, and the time frame.

Is there anything I should add, or try to clean the rocks myself? Or am I just overreacting and it is a relatively immature tank that needs to cycle a few times for things to be orderly?

Thanks to all who answer, and I apologize for the long post!
