The fountain does not seem to keep its water pressure and the water stream will start to get slower and spill out over the sides. However, to fix this- ALL you have to do is add 4 cups of water every day or so (when you notice the water is not flowing good. I pour this directly into the bottom bowl where the water flows. So I don't have to remove the fountain top attachment. Now this may not matter if you keep your fountain outdoors but I keep mine INDOORS and don't want the carpet to get moldy or discolored. So I also bought a water drying mat (like you use to place dishes to dry) to put under it in case any water does splatter over the edge. I added some small plants to sit on the edges. And last but not least, I bought some small blue LED string lights (which are waterproof) to wrap around the bowls to add ambiance. Turned out very well and I am very pleased with this purchase and my Bohemian/reading/guest room.
