Water question

[FLARE1516]

Ok my daughter has a 1.5 gallon tank with 1 betta (RJ). Within a day or two of cleaning (100%) the walls of the tank, the gravel and the decor begins to have this brown film on it. There is no filtration. Could the temperature of the room be causing it to "mold" (for lack of better term) faster? she has an upstairs bedroom and it is warmer in there than other rooms.
Any thoughts or suggestions please.

Thanks!!!

Sounds like it could be algae. My only thought is keeping the tank clean as needed. I believe they do make products out there to eliminate algae in tanks. I've never used it, so I have no experience. Good luck though!

Yeah I agree, clean your tank. I also have algae med. But I don't have algae problem. When I clean tank I also clean the decor.

yea once in a while it happens in my tanks that tend to get warmer, its algae.
