How do I keep outdoor fountain water clean?
I just made an outdoor garden fountain for my balcony....and I love it!! What would anyone recommend I add to water so that it does not get slimy or get nasty. It is a large planter type pot with another planter type pot within it and then I added a pump that can bubble or spray...but water is retained in the pots at all times. I also have cats and dogs...so I would like the additive to be safe (I do not let them drink fromit...but just in case) Thank you!!!
