Algae

I am new to saltwater and wonder if it is common to have to clean your glass of algae everyday? If i leave it for 3 or 4 days it covers the glass pretty good. It is a reddish brown color and when it is cleaned off the glass, it comes of like dust.
My tank is washed in sunlight on all four sides. Not direct sunlight just washed over the tank from the windows. My halides are on from 10 am till 7 pm.

There is no algae growing anywhere else. just the glass

My calcium is at 420
Alk is 10
Mag is 1200
Almost zero ammonia and Phospates
Ph is 8.2

2nd issues is my green torch has been growing like crazy, it went from about 3 inches to about 7inches in 4 months and then is a span of about 4 days it is almost dead. Three of the 5 heads are dead.

Any ideas what may have caused this.

My tank is pretty consitent. The temp stays at 78, plus or minus 2
I use dosers for the cal, mag and alk. Nothing new was used in the tank.

I did notice that my cocoa featherduster retracted in about the same time and is now starting to come out. This was about the same time the torch seemed to quit dying too.

I had another SPS that died just before the torch started to go. That sps was introduced into my tank about a month ago, it was doing great, then about a week ago it died, then the torched started to die and the feather duster retracted. My hammer coral is doing fine, as are any softies and LPS

Any help is appreciated
