EasyCare ProTec Scale and Stain Remover, 8 oz. Bottle

Works pretty well, used in my outdoor fountain seem to reduce algae. Not so much with the indoor fountain. Perhaps inside temps. Good price on Amazon.

Good product .

I use this formula in my indoor & outdoor fountains & it works great!

We have extremely hard water that quickly discolors our three fountains (metal and stone). We tried calcium and lime dissolvers with fair results. Then we tried EasyCare ProTec Scale and Stain Remover and were amazed at the results. It works quickly and keeps stains at bay for months, not days or weeks. I do wish it came in a spray bottle for a more controlled direct application on areas where the build up is more pronounced, but I'll pick up one myself. Looking forward to sitting next to one of our fountains while sipping an iced tea, rather than stressing over lime and scale build-up.

I wish I had taken before and after photos. I used a whole 8oz bottle in a large outdoor fountain that was crusty white everywhere that was splashed by water. Now after a month the white is almost gone in all the areas that are constantly splashed. The areas that receive less splash are still white. I am optimistic that if I clean those areas by hand, EasyCare will keep them clear.
