Not sure if you are still living with white crud in your fountain, but for others: This from a pool center blog: Calcium Hardness When we speak of scale, we are talking about calcium carbonate which has come out of solution and deposited itself on surfaces. It is a combination of carbonate ions, a part of total alkalinity and calcium, and a part of the Calcium Hardness level. The test for Calcium Hardness is a measure of how "hard" or "soft" the water is. "Hard" water can have high levels of calcium and magnesium. If these levels are too high, the water becomes saturated and will throw off excess particles out of solution which then seeks to deposit themselves on almost any surface inside the pool. They can be attracted to ladders, lights and in extreme cases deposit themselves as very small crystalline clumps - all over the pool surfaces. Calcium Carbonate scale; a "white-ish," crystallized rough nodule. ----------------------------- Water in Mexico is typically really hard. Basically, this blog is saying that if the calcium content of your fountain water is too high, you'll get scale everywhere. Depending on the volume of your fountain reservoir, you could try an easier solution than elbow grease: Partially drain the fountain, and then add back distilled water (free of minerals). If that doesn't do it in a couple of weeks, then add some more distilled water. The fountain water itself will absorb back the calcium deposits to get back into balance. Here's one source of distilled water in bulk in Guadalajara: Ecosource Guadaljara cel: 33 1279 3240 Good luck!
