Algae on the sand bed

[sbazain]

I had t5s and never had algae on the sand bed now that I have LEDs I have green algae not hair algae just green algae as a matter of fact my rocks are getting coralline and getting green at the same time, my LEDs are full spectrum don't know if its to much whites or to much blues what do you think

Its to much light for what your tank is used to, but, don't worry about it, keep it blown off and it will go away in a few weeks. I had the same thing switching from Halides to LEDs. You could lower your intensity, then slowy over the next few weeks bring it up, that would also help, instead of going full blown LED right off the bat.

"Green coralline" is actually regular coralline that was eaten overnight, and has grown a thin film of algae on it.

Yes I brought down the intensity and going to give it a few weeks and gradually bring it up do you think going full blown blues will harm the corals I mean little by little until I get there
