White film on glass

[Chiefmaster30]

What has caused my typical film on the inside front glasses my tank to start becoming white? Typically it's usually brownish in color or light greenish. The past 3 days it's gotten whiter and whiter.

Mine does that when I dose carbon

My tank (Red Sea Nano 28) lookes very similar while I was using the Red Sea Mature Kit for Cycling. Others on this forum suggested is was because of Carbon Dosing. Mine turned out to be some kind of Bacterial Bloom which took a week to die off, then I was left with a mess of Yellowish White stringy slime to clean up.

What a mess.

Yes, I have had blooms do this also.
