The One Cleaning Solution to NEVER Use On Your Large Garden Fountains
The One Cleaning Solution to NEVER Use On Your Large Garden Fountains Adequate care and regular maintenance are important to the longevity of water fountains. A typical problem with fountains is that they tend to gather dirt and debris, so it is vital that you keep it free from this. Also, algae has a tendency to build up any place natural light meets water.
No more than 3-4 months should go by without an extensive cleaning of a fountain. First off you must remove the water. Then use a soft cloth and gentle cleanser to scrub the inside. A good tip is to use a toothbrush if there are tiny hard-to-reach spots. Do not leave any soap residue inside of or on the fountain.
Various organisms and calcium deposits can get inside the pump, so it is best to take it apart and clean it completely. Soaking it in vinegar for a while will make it easier to scrub. Mineral or rain water, versus tap water, is ideal in order to avoid any build-up of chemicals inside the pump.
Finally, be sure to have a quick look at your fountain every day and add water if you see that the level is too low. If the water level falls below the pump’s intake level, it can damage the pump and cause it to burn out - something you do not want to happen!
