i have a feeling he is just talking about the build up that grows on the glass when you dont clean it every day.As Edison mentioned , Keep an eye on oxygen levels
If it was me , I would do some water changes over the next few days , I would also turn the lights off for a couple of days , Feed as little as you can get away with and wet skim the hell out of it :)
But yes we need pics :)
Nope, that is really thick. The one I have is a thin layer of green covering all of the glass. Will take photos / video tonight.Does it look like this?
