1) High alkalinity
2) reduce lighting period for a few days
3) push the calcium levels up
4) I personally set up a canister filter and attached an old toothbrush to
the suction end, then I reached in, toothbrushed the algae which was sucked
into the canister filter (magnum 350).....it's been under control for 2
months now.....but tank age is a factor as well....it's just a natural part
of the cycle, especially if you don't use RO.DI water.

I have lots of green hair-like algae growing on my live rock. Is there an
easy way to physically remove this algae?
