How to Eliminate Calcium Deposits

To extend the life of your fountain and keep it looking its best it is going to require routine cleaning. It does not matter what size it is, or if it is kept inside or outside; it is susceptible to white scale and algae. Not only does this diminish its appearance, it reduces its lifespan. Take care of your fountain properly, and it will last you a long time.

Creating a Schedule

The location of the water feature will typically dictate how frequently it needs to be cleaned. Large indoor ones that are away from direct sunlight usually only need cleaning every other month. Small tabletop fountains should get done monthly. Smaller pieces have less water, and this smaller volume makes it harder to dilute white scale and algae. Outdoor water features generally need cleaning at least once a month. Those in direct sunlight need cleaning more than those in the shade. However, fountains in shade typically fill with leaves in the fall and will need cleaning more frequently then.

Cleaning Guide

  • Turn off and remove pump and stones.
  • Empty water.
  • Clean using a nonabrasive sponge and cleaner.
  • Use CLR to remove buildup.
  • Rinse, wipe out, and rinse against to make sure there is no cleaner left behind.
  • To clean the pump, remove the face to expose the propeller.
  • Use a toothbrush to scrub inside and rinse with water.
  • Clean the tubing. You can actually soak this in soapy water or a solution of vinegar and water while you clean the fountain.

While Scale and Algae: Elimination and Prevention

White scale can be a pain to clean, especially if you can actually see it. If it has gotten to the point where it is visible there is a significant buildup there. These tips will help.

  • Vinegar and Water - Nearly everything can be cleaned with vinegar and water, and this includes your fountain. Spray it on, and allow it to sit for a bit before wiping clean.
  • Lemon Juice - Similar to vinegar, lemon juice works best when sprayed and left to sit.
  • CLR - For tough stains, a basic calcium lime remover from your local home improvement store will work. Always make sure you use a nonabrasive sponge.


Preventing algae and lime scale is a lot easier than cleaning it. Distilled water is ideal, but not necessarily practical for large pieces. If you have a large fountain, use a product that works with regular tap water to create a protective barrier against scale and algae. Protec Scale and Stain Remover is a popular product for this purpose.
