I remember when my GW bout first came on, and it looked like a bacterial bloom. There was no greenish tint to it at all. But it went away at night and came back by day. So I knew it had to be, but I didn't believe it. Then eventually (it's hard to tell exactly when because it happens gradually) I looked at my tank and there was no longer any way I could deny it-- the water had taken on a greenish tint.
So to the store I went, to buy a UV filter, and I lived happily ever after...
