Aquarium Sand Turning Brown ?

Has anyone ever had the sand in their aquarium turning brown? If so why does this happen?

It started off as a very fine white sand, and its been about 3 months now that the tank has been cycled. It just started happening about a week ago. It is also mixed with some small gravel.

I have 2 honey gouramI ,1 nerite snail, and a bunch of pest bladder snails.

Irv Welcome to keeping "Wet Pets" and all that can happen.
More than likely you have a Diatom bloom (aka Brown Algae). Some tanks get them and others not so much. Do a search to find out more.

Sounds like a diatom bloom to me too. Common in a cycling tank and, while not pretty, isn't the worst thing to have. Diatoms wipe off really easily and will eventually clear up on their own once the tank is mature.

Do you have any pictures showing the before/after. Is there soil under the sand, do you have live plant's?
Here's some pictures. Unfortunately I don't have any before pictures. And yeah I have some java fern and dwarf lily. The middle picture is right corner where it still looks pretty white.
