Hey everyone, Aquaman here with Water Wisdom sponsored by WaterFilters.NET. Today's product is the PolyGuard polyphosphate filter from Pro Products. Now, we use the word filter because this fits inside a standard filter housings like the HF-360 or HF-150, but it's really not a filter, because it's not removing anything from the water, it's actually adding polyphosphate into the water. Now, polyphosphate is a sequestering agent. It does really two things; first it coats all metal surfaces with a microscopic coating of polyphosphate. This makes it difficult for hardness and scale to form on those surfaces. It also makes it difficult for acid water to eat away at those plumbing parts, those plumbing pipes and such. It also sequesters iron and mineral hardness in the water solution. The little iron molecules and hardness molecules want to join hands and form scale in the water as they’re floating through the pipes. This will encapsulate them and make it so they can't join hands and form larger particles that then form scale. So it sequesters them, it neutralizes them. It's not a water softener, but it does have the effect of reducing scale, and reducing the staining effect of iron in water. It's only going to be effective in water that is between 6.5 and 9.0pH and below 12 grains per gallon hardness. The closer you get to 12 grains per gallon, the less effective it's going to be. So lower hardness, much more effective, very low iron, if you have above 1 part per million of iron forget about it, this is not the appropriate product for that situation. It fits inside standard filter housing like 10 inch by 2.5 inch filter housings. And it's from Pro Products, American made products, available at WaterFilters.NET. I'm your host Aquaman and thanks for watching.
