i think i have a sick fish :-(

Question
Hello, I have had my fish for almost 2years and it has always been perfect, nothing has ever been wrong until a month ago. My beta fish's water turns bright GREEN within a day or two of changing it. I have done everything, I changed the water almost daily, I clean the bowl very well. But the water just seems to get very foggy and very green really soon.  

Answer
you might of had an algae bloom and after u clean it it comes back from a little bacteria stuck on somthing i would try algae gone and see if that works do you have a light on near the fish tank that lights it up if so your problem is from leaving the light on i wouldn't leave the light on more then 8-10 hours a day
