Turf algae

[Moke]

I came home from a couple weeks out of town to find turf algae - I think that's what it's called. It's reddish/purple and hard to pull off the rocks. My parameters are:

Ammonia 0
Nitrites 0
Nitrates 5-10 ppm
pH 8.1 - 8.2
SG 1.025
Phosphate ?
Alk 9
Temp 78

I have 150 watt MH lighting for a 75-gallon tank, use Scripps water and top off with RO/DI water. All animals look fine, is there something that will eat this stuff? Or another way to control it?
thanks in advance...
