Leave it, they will burn themselves out.

Leave it, they will burn themselves out.

Is there a ballpark est. as to how long that should take?
I just noticed the same type of brown "stuff"
It seems to be almost unnoticeable in the morning when the light first turns on and gets darker throughout the day.

Ballpark...not really, it depends on the lighting and type of sand or how much silicate is in the tank. If I had to do an average, MAYbe a week, but it will be there one day and gone the next.

This is kind of embarrassing to admit but I have a 90g FOWLER with just a standard, ceiling fluorescent light bulb- I leave on for a about 13 hrs...should I change that out? Reduce daily hours of lighting?
(sorry for hijacking your thread hagerman )

For FOWLR, you should be ok. Personally, I run my lights for 8 hours....
