To ensure that water fountains last a long time, it is vital to perform regular maintenance. It is essential to clean it out and remove any debris or foreign objects that might have dropped into or onto it. Another factor is that water that is subjected to sunlight is vulnerable to growing algae. Either sea salt, hydrogen peroxide, or vinegar can be dissolved into the water to avoid this issue. Bleach can also be dissolved into the water, but this is not the ideal option because it can harm birds or other animals.
Every 3-4 months, garden fountains should have a serious cleaning. Before you start cleaning, all the water must be eliminated. When you have done this, scour inside the water reservoir with a gentle detergent. A helpful tip is to use a toothbrush if there are small hard-to-reach spots. Do not leave any soap residue inside of or on the fountain.
It is highly advised taking the pump apart to better clean the inside and get rid of any plankton or calcium. Letting it soak in vinegar for a few hours first will make it alot easier to clean. Mineral or rain water, versus tap water, is ideal in order to prevent any build-up of chemicals inside the pump.
And finally, active make sure the water level is consistently full in order to keep your fountain operating smoothly. If the water level slides below the pump’s intake level, it can hurt the pump and cause it to burn out - something you don't want to happen!
