Wall Water Features

What water treatments can you put in a water feature?

I have brought a small water feature to put on the shelf in my room. It only takes about a pint of water so it's not a big feature at all. Having spoken to a friend about it he advised putting a water treatment in because apparently the water will go murky. Any advice on what to use or will it be ok? it's an indoor water feature. Thanks

1. indoor should not be too bad. replace the water with fresh chlorinated tap water once a month. if it gets too much sunlight you will get algae growth. large outside recirculating features need a little copper sulfate rock to kill the algae as the chlorine in the supply water evaporates off in a day or two.
