Lucky Bamboo and yellowing leaves

Question

My lucky bamboo's leaves tips started turning brown so I moved it to get more light. This increased the problem. Just read that direct sunlight is a no-no. Now, the leaves are yellow to almost white. I read that the most likely situation is too much chlorine from tap water. We have a well, so I don't think that is the problem. I don't fertilize, but I read that they really don't need fertilizer. I will check to see if it is root bound. It is growing in rocks in a painted container, so I will have to remove to analyze. However, I don't think that this is the problem either. I will remove out of the sun, clean the water once again and check the roots. If this does not work.......any suggestions? Thanks
