Red Powder Stuff on my glass??

[shaunj]

Everyday without fail, i get this thin layer of red like powder on the inside of the glass on my 49g reef... When i have my MH on, it grows alot faster... It coats all of the glass, and comes off really easy with magnet cleaner... Any ideas as to what it is?

i had a tank that did the samething, it was about the six of a golfball. i cleaned it everyday, for about 2 months then it went away. i thought it was cyano also, but that is the only place it ever showed up.
JDM...

I know what cyano is, and it isnt that, unless it is a different form... Pretty Strange huh?!
