Really like the sound of this fountain. I used half distilled water and half tap water, only because I thought I had bought enough distilled for it but it takes a lot of water to fill. I have found that using the tap water is fine and have had no problems at all with it so that is nice to not have to buy distilled all the time as you do need to top it up every other day. The lights are dull at night but they are pretty with the way they reflect off the rocks at night. One thing I didn’t like was the hose connection as it kept coming off in the unit but it seems to be staying on for now.
